Variable discharge gear pump. |
摘要 |
An improved variable discharge internal gear pump having a pump housing (1, 1a) and a gear set mounted in the pump housing and consisting of an outer rotor (3) and an inner rotor (4). The relative position between the gear set and the suction port and the discharge port formed in the pump housing are variable, thereby making the discharge volume variable. Three means for this purpose are proposed.
