Subject of the invention is an eccentric pump with lock valve, mainly for the lubricant circulation of drives, provided with case of inner cylindrical surface fixed with tangential support and having pressure and suction connections, furthermore with shaft sealed and voncentrically embedded leading through the case, liquid chamber closed between the case and the shaft, confined by parallel planes on the side, round eccentric part arranged on the shaft, rectangular sectional ring pressed to the cylindrical inner wall of the case by the eccentric part in a point of contact moving from the pressure connection to the suction connection, as well as a lock valve separating the suction and pressure connections from each other by way of sealing. According to the invention, the lock valve is formed as an externally tangentially support pin (9), the end of which is flattened inside the case (1) and fixed in the radial hole of the case (1) communicating with the suction and pressure connections (7,8), while the ring (4) pressed by the eccentric part to the inner wall of the case (1) is provided with a radial slot (10 ) connected to the flattened end of the pin (9) by way of self-adjustment and sealing. |
