专利摘要:
A fuel pumping apparatus includes a housing in which is located a plurality of reciprocable tappet assemblies including tappet bodies. The tappets carry rollers for engagement with cams respectively. In order to prevent rotation of the tappet bodies adjacent pairs of the tappet bodies are provided with mutually facing and mutually inclined flats which are engaged by wedge-shaped guide members. The flats and guide members permit reciprocable movement of the tappet bodies but prevent rotation thereof.

专利说明:

The invention relates to engine manufacturing.
Known fuel> 1st pump for an internal combustion engine, comprising a housing with through holes for plunger pushers having guide surfaces in the form of flats, a cam shaft for interaction with pushers and a guide device of pushers fl mounted on the housing
The disadvantage of this pump is the complexity of the design.
The purpose of the invention is to simplify the design.
This goal is achieved by the fact that the guiding device is made in the form of a plate with wedge-shaped elements, and the flats of adjacent pushers are facing one another for interaction with wedge-shaped elements.
The plate is made integral with wedge-shaped elements.
In FIG. I shows a fuel pump, plan view; in FIG. 2 - the same, partial section, side view.
The pump contains a housing 1 with through holes 2 for plunger pushers 3 having guide surfaces in the form of flats 4, a cam shaft 5 for interacting with pushers 3 and a guide device for pushers fixed to the housing 10 1
3, which is made in the form of a plate 6 with wedge-shaped elements 7, while the flats 4 of the adjacent pushers are facing one another for interaction with the wedge-shaped elements 7. The plate 6 is made integral with the wedge-shaped elements 7.
The pump operates as follows.
When the cam shaft 5 rotates, it acts on the plunger pushers ‘3, which make a reciprocating motion. The wedge-shaped elements 7 of the plate 6 of the guide device 25 ensure the fixation of the tolkaz 906393 of the bodies 3 from turning around its axis.
Thus, the proposed pump has a simple design in terms of fixing the pushers from turning.

Claims (2)
[1]
39 telles 3 due to turning around (ani around its axis. Thus, the proposed pump has a simple constructive implementation in terms of fixing the pushers against turning. Claim 1. Fuel pump for an internal combustion engine containing a housing with through holes for plunger pushers having lisok guiding surfaces, camshaft for interacting with pushers and a pusher guide device mounted on the housing, characterized in that, in order to simplify the design, The device is made in the form of a plate with wedge-shaped elements, and the flats of the neighboring pushers are turned one side to another to interact with the wedge-shaped elements.
[2]
2. The pump according to claim 1, distinguishing it with the fact that the plate is made integral with the wedge-shaped elements. Sources of information taken into account during the examination 1. French patent no. 1589835, class F 02 M ,. publish 1970.
