专利摘要:
The lever (13) on the one hand co-operates with a rotatable element (12) and on the other is coupled with an alternating actuator (14), whereby the lever consists of a housing (15) penetrated by said rotatable element (12), of a piston-shaped spring washer (16) and of a return spring (19) tensioned between the housing (15) and spring washer (16). The spring washer (16) and rotatable element (12) form in the mutually co-operating region a torque-limiting entrainment device. The hollow space (25) under the spring washer (16) can be subjected to oil pressure via holes (21, 22) in the rotatable element (12) which are controllably linked with a source of pressure (24). The oil pressure moves the spring washer (16) so that the entrainment device is released. Irrespective of the position of the rotatable element (12) the lever (13) is then set by the spring (27) of the alternating element in an end position which corresponds to the zero delivery position of the fuel injection pump (11).

专利说明:

The invention relates to the automatic regulation of internal combustion engines, in particular, to devices for regulating high pressure fuel pumps.
The purpose of the invention is to increase reliability.
FIG. 1 shows a regulating device, a cross-section; in fig. 2 fuel pump with control device and control elements.
A regulating device for setting the performance of the high-pressure fuel pump 1 comprises a regulator (not shown) connected to the regulator. TURNING organ 2, interacting with the latter lever 3 and coupled to lever 3, and executing a reciprocating actuator 4. Lever 3 consists from the housing 5. in which the plate 6, spring-loaded spring 7, and the stop 8 are arranged in the form of a lorshn, the spring 7 is located in the annular gap 9 formed by the housing 5 of the lever 3 and the tray 6 and is clamped between the plates 6 and the second abutment 8.
The spring plate 6 has a prismatic extension tO on the side facing the rotary body 2, which, with its end surface under the action of the spring 7, abuts the flat part of the rotary body 2. The plate b and the rotary body 2 form in the interaction zone with each other a torque-limiting driver. .
The rotary body 2 also has an opening 11 parallel to its longitudinal axis, which through an adjustable valve 12 is connected to an oil pump 13, for example, an internal combustion engine lubrication system. In the area of the driving device of the hole 11, in the radial direction in the body of the rotary body 2, an opening 14 is made, which communicates with a gap 15 formed between the body 5 and the rotary body 2. Furthermore, between the outer surface of the prismatic extension 10 of the dish b and the inner surface of the body 5 a hollow space 16 is formed, and the actuator 4 is spring loaded by the spring 17 to the final position.
The control device of the fuel pump works as follows.
When the adjustable valve 12 is turned on, the oil from the oil pump 13 begins to flow into the opening 11: As soon as the opening 11 is filled with a pressure shaft, the oil penetrates the cavity 16 through the gap 15. Due to the pressure created in the hollow space 16, the plate
6, the spring is pressed against the stop 8. As a result, the connection between the prismatic extension 10 of the plate 6 and the plane of the rotary body 2 is eliminated, and the torque transmission by the retaining device is stopped. Now the spring 17 reciprocating the actuator 4 presses the lever 3 to the left end position corresponding to the zero feed,
regardless of the position of the rotary body 2.
Other high-pressure fuel pumps not shown in the drawings, which are controlled by the rotary body 2 and have an orifice 22 in the lever 3, are switched in the same way.
The hydraulic disconnection of the powered device prevents the occurrence of reactive torque at
rotary body 2, which eliminates the effect of disabled fuel pumps, high pressure pumps on the operation of the regulator.
F o rm l a and 3 o b r e t y n i
A high-pressure fuel pump regulating device containing a lever, a pivoting member cooperating with it and an actuator coupled to the lever mounted for reciprocating motion, the lever being designed as a housing with a through hole and located in the housing of a spring-loaded plate
with the piston, and the rotating body is installed in the outer hole of the body levers with the formation between the rotating body and the spring-loaded plate of the driver pair to limit the torque two holes, the first of which is parallel to the axis of the rotary member, and the second - in the radial
direction and communication with the zone of interaction between the spring-loaded plate and the rotary member, the plate being installed in the housing with a closed cavity between them and both
