The pump of high pressure - general information, removal and installation
General information
|
|
The pump is put in action by means of a maple belt. The pump has a piston design. On an illustration the cross pump of the pump is presented. |
Six pistons are set in motion from the special shaking disk put on the needle bearing. Hydraulic liquid comes through four openings to each of cylinders, then via the spring backpressure valve under pressure comes to a hydraulic contour of system. Restriction of the pressure developed by the pump is made by means of the special regulator of pressure, placed in the general case with the main accumulator (receiver). Removal of air from the pump is made by an otpuskaniye of the spuskny gate of the regulator.
