The pump has a housing with meshing gears, a pressure pipe for hydraulic fluid feed, and a fluid suction pipe. A pressure limitation valve (17) is located in the bearing body (11), and frees resp. blocks a bypass channel (20) between pressure pipe (16) and suction pipe (15). A bearing body (10,11) is located on the longitudinal sides of the gears. The valve is formed by a spring-loaded sealing element. The spring (19) has adjustable tension. The valve is remote controlled. |
