Abstract

Hydraulic pump has control stub (2) which exhibits two control surfaces as well as lies in axial direction beside the rotor (1) and with two control surfaces to its front end, each of which is connected with each piston area, parallel to the axis of rotation and axially running and discharge drilling (3a), is provided at the front side of the rotor. Each line connection of the suction non return valve (5,6) is connected to front and back annular channel (5a,6a) circulating between the housing (12) and the casing of the control pin arranged therein. The front annular surface of the annular channel is formed from an area of the control pin with decreasing radius whereas the front annular surface is limiting the annular channel at its adjacent side close to the front surface of the rotor and the rearward annular surface limiting the annular channel at its side remote to the front surface of the rotor is formed from an area of the housing.
