专利摘要:
A master cylinder of the quick-fill type has an open-ended pressure cylinder closed by a closure member and a reservoir mounted on the cylinder. The closure member partially defines a quick-fill chamber in which slides a piston connected to a piston of the pressure cylinder. A valve controls communication between the quick-fill chamber and the reservoir.

The invention relates to hydraulic brake systems of automobiles, in particular, to the main brake cylinders of rapid filling. The purpose of the invention is to simplify installation and maintenance. FIG. 1 shows a part of the main cylinder, a longitudinal section; in fig. 2 - part of the main cylinder in another embodiment, longitudinal section; in fig. 3 is a part of the following embodiment of the master cylinder; The master cylinder of the braking system of the double circuit (Fig.) Contains pressure cylinder 1, presented as a thin-walled pipe with a wall of equal thickness, having an axial blind channel with a working chamber 2 whose open end is closed element 3. The rear piston 4 of a pair of pistons located in the channel is provided with a seal 5 and has a sleeve 6 extending backward, in which the driving rod 7 is placed, which is connected in the usual way with the operating element 8 of the amplifier, having the first sleeve 9 of the power piston and the housing 10. The cylinder 1 is mounted on top tank 11 which communicates respectively with the internal chamber of the cylinder through the openings 12 and 13 formed in the cylinder 1. rtenke. The closing element 3 includes a sleeve 14 in Seb, having a relatively large diameter compared to cylinder 1 and partially forming a fast-filling chamber 15 having a relatively large volume. The open end of sleeve 14 is closed by a cap-shaped piston 16 sliding inside sleeve 14, and the base 17 of the piston 16 has an opening for passing through the rear end of the sleeve 6. This base 17 is firmly held between the radial flange 18 of the sleeve 6 and the retaining ring 19 placed in the groove of the sleeve 6. Thus, the pistons 4 and 16 move together as one organ when subjected to a force, transmitted through the rod 7. The closing element 3 is fixed in place jmopoM in the fixing flange 20 of the cylinder 1 pressure by means of the casing 10 amplifier, which, in turn, is pressed to this flange by a spring 21 constituting part of the amplifier mechanism, clamping the flange 22 of the sleeve 14 between the casing 10 and the flange 20. The sleeve 14 has an axially extending tubular extension 23, the opening 24 of which provides communication between the rapid filling chamber 15 and the valve device 25 for adjusting work quickly filling chamber. The extension 24 is in a sealed connection with the valve device body 26, located inside it, and the channel 24 continues with a corresponding channel 27 inside the housing 26, branch 28 leads to the valve device chamber 29. The housing 26 is located in the recess 30J formed between the body of the reservoir 11 and the pressure cylinder 1, and this housing is in a sealed connection with the reservoir due to a sealing ring 3 located around the reservoir opening 32 on the support ring 33, which serves to support the possibility of communication between the hole 22 and the chamber 29. The valve device includes an element bearing a seat 34, tightly seated in the annular gap between the central cylindrical protrusion ohm 35 of housing 26 and inner wall of chamber 24, tubular first valve element 36 having an outwardly directed ledge 37 supported on element of saddle 34 j and spring 38 operating between bearing ring 33 and protrusion 37 for pressing valve element 36 against saddle 34 sv house them in a hermetic connection. The upper end of the valve element 3 (FIG. 1) has a through hole 39 that forms a valve seat designed to interact with the second valve element in the form of a ball 40, and this design works as a one-way valve, and inside the valve element 36 the ball is held by protrusions 41 When the master cylinder is operating, the pistons 4 and 16 move together and the fluid is displaced by the piston 16. It is fed from the rapid filling chamber 15. The force of the spring 38 is chosen such that the pressure originally generated by the piston 16 does not lift up the valve element 36, which is pressed by the spring 38. Since the pressure causes the ball 40 to close the opening 39 in the valve element 36, the fluid from the rapid filling chamber 15 bypasses the seal 5 piston 4, entering the chamber 2 ,, and from there into the brake system, where it quickly fills the brake chambers in a known manner. When the pressure in the chamber 2 increases to a value that prevents further fluid flow from the rapid filling chamber 15 to the chamber 2, the valve element 36 is led out of the joint with the elastic seat 34, thanks to which fluid from the fast filling chamber 15 passes through the axial channel 24, bypassing element 36, and through hole 32 passes into the reservoir. The seat element 34 has a groove 42 on its upper surface, preferably of a spiral configuration, which facilitates the flow of fluid between the valve element 36 and the seat 34. When the pistons 4 and 17 return to their original position after braking, the ball 40 moves down, away from the valve hole 39 element 36 at a distance. bounded by the protrusions 41, thus making it possible to transfer fluid from the reservoir to the rapid filling chamber. FIG. 2 shows another embodiment of a valve device in which the arrangement and operation of the components are substantially similar to the arrangement and operation of parts of the above embodiment shown in FIG. 1, However, in this embodiment, the elastic element of the seat 34 forms a subassembly with a base 43, which is connected to the top by crimping a protruding part 44 having clipped lateral edges 45. The base 43 forms an extension 46 of the axially charged channel 24 of the sleeve 14 In this embodiment, the valve elements are inserted into the chamber 29 by inserting them h (the upper end of the housing 26 before the installation of the support ring 33, which in this case is a screw-cut element designed to be connected to the housing. Fig. 3 shows the following valve arrangement design. In this embodiment, the arrangement and operation of the valve components are identical As described in accordance with FIG. 2, except that the housing 26 is bypassed and the valve mechanism is located in the compartment formed by the tank body and its constituent part. For this, additional The wall 47 extends downwardly to the connection with the pressure cylinder 1 and has an opening for receiving an axially directed part 23 of the sleeve 14 of the closing element. In this embodiment a separate base 43 is also used, on top of which the elastic element of the saddle 34 is held in the manner shown in FIG. 2, However, in this embodiment, the valve components in the compartment are assembled from the underside of the tank, and the base 13 installed in the position shown is permanently attached to the tank by a weld 48, with the result that the valve device 25 and the tank now form a single unit. the invention formula 1, the main brake cylinder of fast filling, comprising a housing, in a cylindrical stepped, open on one side of the channel of which pistons of different diameters rigidly interconnected by a connecting element, a reservoir, a valve device connecting the reservoir with formed by a step of a larger diameter channel of the housing and a large piston with a fast filling chamber, a lip seal on the small piston, ensuring the flow of fluid from the rapid filling chamber The valve device housing is located in the recess of the tank housing. The valve device includes a seat surrounding the channel in communication with the rapid filling chamber, pressed against the seat, with a spring on the tank side, a first valve element with an axial bore, and a second axial bore valve seat
