PURPOSE: A flow-controlled cell pump including a pivotal control slide valve is provided to reduce operation noise and to minimize the vibration resulted from pressure pulsation. CONSTITUTION: A flow-controlled cell pump including a pivotal control slide valve(1) comprises a drive shaft(3), an internal rotor(4), a bearing lug(5), a bearing element, an acceptance cell(7), a suction kidney(10), a pressure kidney(12), a control slide valve arm(13), and a spring. The bearing element is a bearing sleeve(16) including an opening(17). A chamber is arranged in the pump housing lid corresponding to both sides of the opening of the bearing sleeve or the pump housing lid arranged at the pump housing(2) and its opposite side, is directly connected to the pressure kidney arranged at the same side of the control slide valve, and is sealed to the suction kidney arranged in a suction side through adjacent assembly. |
