The method includes designing the suction pipe by: selecting a first dimension for the primary portion of the suction pipe, calculating a first fluid velocity for fluid in the primary portion based on the first dimension, and comparing the first fluid velocity to a first predetermined threshold; selecting a second dimension for the secondary portions, calculating a second fluid velocity for fluid in the secondary portions based on the second dimension, and comparing the second fluid velocity to a second predetermined threshold; and calculating a ratio of the first fluid velocity to the second fluid velocity.

An internal gear pump includes a pinion, a ring arranged around the pinion, and a cylindrical wall arranged around the ring. A support element, on which the pinion and the ring are supported, carries high-pressure liquid towards a recess located at the junction between the ring and the cylindrical wall, and also carries low-pressure liquid towards another recess located at another point of the junction between the ring and the cylindrical wall. The recess allows the load of the ring on the cylindrical wall to be reduced.

This pump comprises: a housing comprising a body and a first partition which separates first and second areas; a stator disposed in the housing; a circuit board disposed in the first area; a pump gear disposed in the second area; and magnets disposed on the pump gear, wherein the second area includes a second space defined by the first partition wall and the body, and the stator is inserted into the body.

A variable displacement lubricant pump includes a housing, a control ring arranged in the housing, an inlet chamber and an outlet chamber, and a lateral slide bearing. The control ring is shiftable, radially confines a pumping chamber, and comprises a drainage channel. The outlet chamber and the inlet chamber are arranged at opposite lateral sides of the control ring. The lateral slide bearing is arranged at the lateral side of the control ring where the outlet chamber is arranged and comprises a first lateral slide bearing surface defined by the static housing, a second lateral slide bearing surface arranged opposite to the first lateral slide bearing surface which is defined by the control ring, and a lateral slide bearing gap defined between the first and second lateral slide bearing surfaces. The drainage channel of the control ring fluidically connects the lateral slide bearing gap with the inlet chamber.

The invention relates to a vane pump for conveying liquids, in particular viscous oils, which vane pump includes: a rotor having sliding slots in which movable vanes are held and can be countersunk in relation to a rotor radius (r); a pump housing including a pump chamber, which encloses the rotor; and an inlet and an outlet, which open into the pump chamber at at least one end face of the rotor; radial elevations protruding, with respect to the sliding slots, over the circumference of the rotor, which elevations form a rotor radius (r) on either side of the vanes that can be countersunk, and radial pockets being recessed, relative to the rotor radius (r), between the radial elevations. Within the radial elevations, recesses are formed on the at least one end face of the rotor at which the inlet and the outlet open, which recesses provide rotating anticipatory control geometry for reducing pressure spikes in the vane cells.
