    A modulating pump is disclosed including a pumping member that is initially operable by a solenoid device in a relatively long full-stroke condition to effect rapid pressure build-up of the fluid supplied to a load, the pumping member being subsequently operated by the solenoid device in a relatively short stroke condition to effect further pressure build-up in the load. A main spring device normally biases the armature of the main solenoid device to achieve the full-stroke operating condition, and when the pressure of the load reaches a value to cause the return force of the main spring to be overcome, a resilient abutment device becomes operable to achieve the desired short stroke pumping condition. A self commutating pump device is also disclosed. The modulating pump device is included in a vehicle traction control system, as, for example, an anti-skid traction control system for automatically braking an overrunning driven wheel relative to another driven wheel connected thereto by a differential mechanism.

    This invention relates to vehicle braking systems providing automatic braking of skidded code. The closest to the proposed technical entity is a device for braking a bukking wheel of a car, comprising a housing in which a pump chamber, inlet, outlet and bypass channels are circulated, the first of which is equipped with a check valve that prevents liquid from flowing from the pump chamber into the inlet channel the second, a check valve, which prevents the flow of fluid from the output channel to the pump chamber, and the third, a normally open solenoid valve; a plunger with the actuator, which is a solenoid, the stator of which is rigidly connected to the housing, and the measles, which can be linearly moved, to the plunger and pushed against the side of the pumping chamber l. The known device has considerable inertia and does not accurately modulate the braking pressure. The purpose of the invention is to reduce the inertia and improve the accuracy of modulating the brake pressure. This goal is achieved by the fact that the device is equipped with an elastic round ring mounted on a crust that can be placed between the stator flange and the core with the spring compressed. The drawing shows a device | for braking a towing vehicle, built-in its braking system, equipped with a system for adjusting the thrust. The braking devices 1 are applicable to a car having a pair of driving wheels 2 and 3 connected by a differential 4. The brake system includes the main brake cylinder 5 and the wheel brake cylinders 6 and 7 on the wheels 2 and 3. The devices 1 are integrated into the brake system between cylinder 5 and cylinders 6 and 7, Each device contains a valve box 8, a pump chamber 9, an inlet channel 10 connected to cylinder 5, an exhaust channel 11 connected to the corresponding cylinder b or 7, and a bypass channel 12, In channel 10 is installed check valve 1 3, in port 11, a pilot valve 14, and in channel 12 a normally open solenoid valve 15 with a solenoid 16, the plunger 17 enters the chamber 9 at one end, the other end of which is connected to the movable wheel 18 of the solenoid 19, the stator 20 of the solenoid 19 is rigidly connected to the x-axis by the device 1. The armature 18 is pressed toward the chamber 9 by the spring 21. At the end of the core 18 in the peripheral groove there is an elastic ring 22 of circular section that comes in contact with the flange 23 of the stator 20 when the core 18 is pulled in 2 and 3 are connected speed sensors 24 and 25 connected to the logs To a common unit 26, which controls the operation of two pulse generators 27 and 28, transmitting uniform 12-volt pulses to the coil of solenoid 19 via wire 29, thereby alternating the excitation and switching off of solenoid 19, the coil of solenoid 16 is connected by wire 30 to generator 27, - A manual control means 31 is connected to block 26 to simultaneously actuate both generators 27 and 28. When the vehicle is moving under normal conditions in the event of braking, brake fluid from cylinder 5 through channels 10 ,. 12 and 11 of each device 1 passes into cylinders 6 and 7 and both wheels brake simultaneously. If, when moving, one wheel, for example wheel 2, rotates faster than wheel 3, the signal from sensor 24, coming to block 26, is greater than the signal from sensor 25, as a result, generator 27 is excited and 12-volt pulses are applied to solenoid 19 coil . At the same time, the solenoid 16 is energized, and the valve 15 overlaps the channel 12. During the first excitation cycle, the solenoid 19 measles 18 is drawn in, moving the plunger 17 to the left, while the liquid from the cylinder 5 is sucked through the valve 13 into the chamber 9. After solenoid 19 is disconnected, measles 18 and plunger 17 are moved to the right by spring 21, pushing fluid from chamber 9 into cylinder 6 through valve 14. During the subsequent excitation and shutdown cycles of solenoid 19, pressure in cylinder 6 increases and overtaking wheel 2 slows down, 06jarra measles 18 relatively long stroke in its reciprocating motion. As the pressure increases in tsitandr 6, spring 21 ceases to translate measles 18 to the right and the latter remains compressed through ring 22 to stator flange 20, while its rking stroke will be determined by the elastically compressible ring 22, thus PRESSURE / cylinder 1ie 6 continues to rise. After leveling3 10775614.
    Neither the speeds of the wheels 2 and 3 block 26 cylinder 5 or the means 31 ensure the termination of the generator 27 and the inclusion of both devices 1.
    the use of the invention permits cylinder 5 to increase the efficiency of the system.
    If necessary, deceleration in general by increasing
    Both wheels are engaged in the operation of pressure in the brake cylinders.
