Abstract: A fluid delivery system includes a reservoir for storing fluid, a rotary pump having a first pump port and a second pump port, a first fluid conduit connecting the first pump port to the reservoir, and a second fluid conduit connecting the second pump port to the reservoir. The rotary pump rotates in a first delivery direction in a normal mode and in a second delivery direction in an alternative mode. A first valve separates the first pump port from the reservoir when the rotary pump is in its alternative mode, and a second valve separates the second pump port from the reservoir when the rotary pump is in its normal mode.

Abstract: A vacuum pump for supplying a machine assembly with negative pressure, the vacuum pump including a housing featuring a delivery chamber which includes a chamber inlet opening and a chamber outlet opening for a gaseous fluid; a suction port for establishing a fluid connection to the machine assembly; a suction channel which connects the delivery chamber to the suction port; and a relief channel which connects the delivery chamber to a relief opening of the housing; a delivery member which can rotate in the delivery chamber in a forward rotational direction and a reverse rotational direction. The fluid is suctioned into the delivery chamber through the chamber inlet opening and discharged through the chamber outlet opening by rotating the delivery member in the forward rotational direction.

Abstract: A pump includes a pump housing including an inlet for the fluid on a low-pressure side, an outlet for the fluid on a high-pressure side, a circumferential wall facing faces axially away from the delivery chamber and on which the outlet emerges; a spring structure arranged on the outer end face of the end wall; a delivery member movable within the delivery chamber for delivering the fluid from the low-pressure side to the high-pressure side; and a securing device for axial securing the pump housing. The securing device includes a female holding element having an axially extending cavity and a male holding element in a joining engagement, exposable to an axial tensile load, with the female holding element in the cavity. The spring structure and/or the end wall is/are held on the pump housing by one of the holding elements by the joining engagement.

Abstract: A rotary pump, preferably a vane cell pump or a pendulum slider pump, includes a stator and a rotor which rotates about a rotational axis within the stator. The rotor includes multiple delivery elements which move radially in relation to the rotational axis, and two adjacent delivery elements limit a delivery cell together with the outer surface area of the rotor and the inner surface area of the stator. At least two delivery cells, preferably two adjacent delivery cells, exhibiting a first maximum cell volume form a first delivery cell group and at least two other delivery cells, preferably two other adjacent delivery cells, exhibiting a second maximum cell volume form a second delivery cell group. The first maximum cell volume of the delivery cells of the first delivery cell group is larger than the second maximum cell volume of the delivery cells of the second delivery cell group.

Abstract: A pump for applying fluid, the pump including: a pump housing, including: a fluid inlet on a low-pressure side; an fluid outlet on a high-pressure side; a circumferential wall surrounding the pump delivery chamber; and an end-facing wall featuring an outer end-facing surface facing axially away from the delivery chamber and at which the outlet emerges; a delivery member, moveable in the delivery chamber, for delivering the fluid from the low-pressure side to the high-pressure side; a gasket including a gasket loop which surrounds the outlet to seal it off on the outer end-facing surface of the end-facing wall; a female joining element featuring an axially extending hollow space; and a male joining element protruding through or from the pump housing or the gasket. The male joining element is in a joining engagement, which can be subjected to axial tensile stress, with the female joining element in the hollow space.
