摘要： A roots pump includes a housing, a rotor chamber, a pair of rotary shafts, and a pair of rotors. The rotor chamber includes a rotor chamber peripheral surface facing a pair of distal end portions of each of the rotors. Each of the pair of the distal end portions includes: a pair of rotor peripheral surfaces facing the rotor chamber peripheral surface with a first radial clearance; and a distal end peripheral surface that is formed between the pair of the rotor peripheral surfaces in the rotational direction and faces the rotor chamber peripheral surface with a second radial clearance greater than the first radial clearance. A width of the rotor chamber peripheral surface facing the distal end peripheral surface in the rotational direction is greater than a sum of a pair of predetermined widths of the rotor chamber peripheral surface facing the pair of the rotor peripheral surfaces.

摘要： A pump, comprising a pump insert which is arranged in an accommodating space of a cup-shaped pump housing. The pump insert comprises a first housing part and a second housing part between which a rotor is rotatably arranged, and a stroke ring which surrounds the rotor and is arranged between the first housing part and the second housing part. A spring flexing along the rotational axis is arranged between the accommodating housing and the second housing part. The spring comprises a spring structure which is made of metal and which imbues the spring with its essential spring characteristics along the rotational axis. The spring is supported towards the second housing part in a region which is arranged in axial alignment with the stroke ring in the direction of the rotational axis, and thus presses the second housing part against the stroke ring.

摘要： A pump fluid driving apparatus includes a housing having a chamber, with two gears mounted within the chamber. The housing includes a first rounded wall section and a second rounded wall section, the first and second rounded wall sections defining at least a portion of the chamber. The gears have teeth located about their respective peripheries and operatively positioned with the teeth of the first gear and the teeth of the second gear intermeshed. The teeth include slotted teeth and solid teeth arranged with uniform spacing in a repeating pattern about the periphery of each of the gears, with each of the slotted teeth having a vane slot and a radially extending vane extending from the vane slot, and each radially extending vane being movable within the respective vane slot and being configured to contact the respective first or second rounded wall sections.

摘要： A seal arrangement for a vane cell pump of cartridge design which is configured such that it can be switched into multiple flows is described. The seal arrangement comprises a first seal which is arranged so as to run around the circumference of a side plate of the vane cell pump, and a second seal which is arranged so as to run around a shaft leadthrough which is provided in the side plate. The seal arrangement is distinguished by a third seal which, apart from at least one first fluid connection, shuts off at least a second fluid connection with respect to the at least one first fluid connection within a region which is configured between the first seal and the second seal.
