Rotary pump with axial compensation, outlet gasket for a pump and pre-fitted pump unit

An outlet gasket which has a gasket structure made of a gasket material, for sealing off a first pressure outlet and a second pressure outlet of a pump and separating the first pressure outlet from the second pressure outlet, the gasket structure comprising:

• a first sealing stay which circumferentially encloses a first fluid passage of the outlet gasket, provided for the first pressure outlet, in a seal in an axial plan view onto the outlet gasket;
• and
• a second sealing stay which circumferentially encloses a second fluid passage of the outlet gasket, provided for the second pressure outlet and located laterally next to the first fluid passage, in a seal in the plan view,
• wherein the gasket structure forms the sealing stays contiguously as a unit, and/or the outlet gasket comprises a support structure on which the sealing stays are arranged, and the gasket structure is fixedly connected to the support structure, and the support structure extends, in the plan view, into the first fluid passage and/or into the second fluid passage in order to form a flow resistance in the region of the respective fluid passage for pressure fluid flowing through the respective fluid passage,
• wherein the outlet gasket has a first flange and a first bulge projecting axially from the first flange;
• the first flange extends around the first bulge and the first fluid passage;
• and wherein
• the first sealing stay extends along the end-face side of the first flange facing axially away from the first bulge and is fixedly connected to the first flange,
• and/or
• the outlet gasket comprises a first circumferential region, made of the gasket material, which extends along an outer circumference of the first bulge and is fixedly connected to the outer circumference of the first bulge, in order to form a plug connection and/or a first radial sealing stay with a pump housing when the outlet gasket is arranged on the pump housing.

A pump for supplying an assembly with a pressure fluid, the pump comprising:

• delivery chamber of the pump, a first end-face wall and a second end-face wall which delineate the delivery chamber at its end-face sides;
• a rotor, which can be rotated about an axis of rotation in the delivery chamber, for forming delivery cells which periodically increase and decrease in size as the rotor rotates, in order to deliver pressure fluid;
• a pump housing comprising a circumferential wall, which surrounds a from a low-pressure side of the pump to a high-pressure side of the pump;
• a pressure outlet which emerges on an outer end-face side of the first end-face wall facing away from the delivery chamber and through which pressure fluid can be discharged from the delivery chamber;
• wherein the pump is optionally a multi-flux pump and has a first flux comprising the pressure outlet as a first pressure outlet and a second flux comprising a second pressure outlet which emerges on the outer end-face side of the first end-face wall next to the first pressure outlet;
• and
• an outlet gasket, which has a gasket structure made of a gasket material, for sealing off a first pressure outlet and a second pressure outlet of a pump and separating the first pressure outlet from the second pressure outlet, the gasket structure comprising:
• a first sealing stay which circumferentially encloses a first fluid passage of the outlet gasket, provided for the first pressure outlet, in a seal in an axial plan view onto the outlet gasket;
• and
• a second sealing stay which circumferentially encloses a second fluid passage of the outlet gasket, provided for the second pressure outlet and located laterally next to the first fluid passage, in a seal in the plan view,
• wherein the gasket structure forms the sealing stays contiguously as a unit, and/or the outlet gasket comprises a support structure on which the sealing stays are arranged, and the gasket structure is fixedly connected to the support structure, and the support structure extends, in the plan view, into the first fluid passage and/or into the second fluid passage in order to form a flow resistance in the region of the respective fluid passage for pressure fluid flowing through the respective fluid passage,
• wherein the outlet gasket is provided on the outer end-face side of the first end-face wall, for sealing off the pressure outlet and, if provided, also on the second pressure outlet.
