The invention relates to a domestic appliance (100), comprising a pump assembly (200) for conveying a fluid, wherein the pump assembly (200) comprises: a housing (202), which has an inlet opening (204, 504) and an outlet opening (206); a drive shaft (208); a first gear (210), which is fixedly connected to the drive shaft (208) and can be rotated in a first direction of rotation (220) and a second direction of rotation of the drive shaft (208); and a second gear (212), which can be moved in relation to the first gear (210). In the first direction of rotation (220), the second gear (212) is in engagement with the first gear (210) in order to convey the fluid from the inlet opening (204) to the outlet opening. In the second direction of rotation, a force can be produced, which moves the second gear (212) in order to release the engagement. | ||||||

A gear pump for power generation comprises a first rotor and a second rotor in a case. The first rotor comprises a first plurality of radially spaced teeth, wherein the first plurality of radially spaced teeth wrap around the first rotor helically in a clockwise direction, and wherein at a first position the first plurality of radially spaced teeth have a helix angle different than the helix angle of the first plurality of radially spaced teeth at a second position. The second rotor comprises a second plurality of radially spaced teeth, wherein the second plurality of radially spaced teeth wrap around the second rotor helically in a counter-clockwise direction, and wherein at a first position the second plurality of radially spaced teeth have a helix angle different than the helix angle of the second plurality of radially spaced teeth at a second position. | ||||||

Die Erfindung betrifft eine Motor-Pumpen-Einheit mit einem mehrteiligen Gehäuse (25), die eine reversible Innenzahnradmaschine (21) und einen Elektromotor (22) mit einem Rotor (22.1) und einem Stator (22.2) umfasst, der über eine in dem Gehäuse (25) drehbar gelagerte Welle (23) mit der Innenzahnradmaschine (21) gekoppelt ist. Die Welle (23) erstreckt sich mit einem Wellenende von der Innenzahnradmaschine (21) weg axial durch den von der Welle (23) getragenen Rotor (22.1). Ein erster Anschlusskanal und ein zweiter Anschlusskanal münden in eine Arbeitskammer der Innenzahnradmaschine (21) und sind über in dem Gehäuse (25) angeordnete Rückschlagventile mit einer Leckagekanalschleife verbunden, die mit wenigstens einem mit der Arbeitskammer fluidverbundenen Leckagekanal fluidverbunden ist und die einen sich axial durch die Welle (23) erstreckenden Leckage-Wellenkanal und einen damit fluidverbundenen, sich axial durch den Rotor (22.1) erstreckenden Leckage-Rotorkanal und/oder einen zwischen dem Rotor (22.1) und dem Stator (22.2) ausgebildeten Leckage-Spaltkanal aufweist, der mit dem Leckage-Wellenkanal fluidverbunden ist. |

A vane pump (20) including: a housing (21), a first motor (23) arranged to rotate a shaft (22) mounted about the shaft axis, a rotor (24) mounted for rotation with the shaft, and a member (28) having a surface (29) and having a member axis. The member is movable relative to the shaft axis through a permissible range of motion which includes portions on either side of a null position. A vane (32) is movably mounted in each rotor slot, and has a distal end arranged to engage the member surface. The vanes define with the rotor and surface a plurality of chambers (33A-33F). The individual volumes of the chambers vary as a function of the relative position between the rotor and surface. A second motor (31) is operatively arranged to selectively move the member relative to the shaft axis through the permissible range of motion. Movement of the member off-null in one direction along the range of motion will enable fluid flow in a first direction between the ports, while movement of the member off-null in the opposite direction along the range of motion will enable fluid flow in the opposite direction between the ports. | ||||||
