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.

摘要： The purpose of the present invention is to suppress the occurrence of unevenness in a rotor of an internal gear pump, suppress the formation of gaps between the end surfaces (side surfaces) of an inner rotor and an outer rotor, and to prevent a decline in volume efficiency. Thus, the pump device of the present invention includes an internal gear pump (10), in which an inner rotor (13) is inscribed to an outer rotor (12), and includes a plate member (7) which is provided to an end surface of the rotors. The plate member (7) is formed of a material having high hardness, has a shape that does not block a suction port (150), has a through-hole (73) formed therein, and has O-ring grooves (71,72), which each have a continuous shape and house an O-ring formed therein.

摘要： A geared fuel pump (4′) operates to supply a determined flow but at low or zero pressure rise. It is planned to add gland packing (46) between support bearings (19) of the pinions (11), or between some of them, to provide hydrodynamic lift for these bearings, by delimiting a closed cavity (47) to provide lift by a fluid with better viscosity properties instead of using the fluid itself that is pumped. Possible application to fuel pumps for aircraft engines, in which the pump (4′) is a high pressure pump associated with a low pressure pump.

摘要： A sliding vane, positive displacement pump is provided which includes a dual mechanical seal that protects against leakage from a pump chamber while also reducing slip across rotor end faces. The dual mechanical seal may be formed as a cartridge seal that is readily demountable from the pump for replacement and service, and is retrofittable to existing pumps to improve the performance thereof. The pump may integrally include a dual mechanical seal, or the mechanical seal assembly may be provided for use by itself or in combination with a replaceable head ring that can be installed on existing pumps for repair thereof or for a retrofit upgrade of such existing pump.

摘要： A rotating pump includes an outer rotor and an inner rotor. The inner and outer rotors are rotated by a drive shaft between a first side plate and a second side plate to pump put fluid. The first side plate faces the inner and outer rotors and has a first surface and a second surface. The first surface is inclined to an axial direction of the drive shaft to create a wedge-shaped gap between itself and one of the inner and outer rotor. The second surface extends more parallel to a direction perpendicular to the axis direction of the drive shaft than the first surface does. The geometric configurations of the first and second surfaces serve to minimize the leakage of the brake fluid without sacrificing a reduction in resistance to sliding motion of the inner rotor and the outer rotor on the second side plate.
摘要翻译：旋转泵包括外转子和内转子。内转子和外转子通过第一侧板和第二侧板之间的驱动轴旋转以泵送流体。第一侧板面向内转子和外转子，并具有第一表面和第二表面。第一表面相对于驱动轴的轴向倾斜，以在其与内转子和外转子中的一个之间产生楔形间隙。第二表面比第一表面更平行于与驱动轴的轴线方向垂直的方向。第一和第二表面的几何构型用于使制动流体的泄漏最小化，而不会牺牲第二侧板上的内转子和外转子的滑动运动的减小。
