FIELD: motors and pumps.SUBSTANCE: group of inventions relates to the field of aircraft engine building, namely to the injection pumps of the turbojet oil system. Displacement pump (DP) is interlocked with the evacuation pump in the casing of the oil unit. Purified oil is fed into the gear-centrifugal working member of the DP. Working member of the DP contains two impellers placed on two parallel shafts. Each impeller has a pinion with a gear ring and a topping impeller. One shaft is connected to the drive, which delivers the torque from the starter and/or the shaft of the HPH, and is equipped with a driven impeller freely mounted on the shaft. Second shaft receives the torque from the first shaft through the gear wheel of the evacuation pump impellers. Working member of the DP works with a centrifugal supply of oil with a topping impeller to the gear rings of the gears and a volume displacement of the pumped medium from the intergear depressions of the interacting gear rings of the gear wheels of the impellers. Displacement of the pumped medium from each of the interacting gears interdental cavity in the corresponding pump is performed in the gear rims rotation angular sector, determined by half the angle formed by gears radii from the relative cylindrical surfaces intersection point describing the gear rims teeth vertices, up to the output point of intersection of the conditional cylindrical surfaces in the direction of rotation of the gears, which constitutes the angular sector β= (0.416÷0.485) [rad]. Angular sector of the subsequent vacuum βin the depression freed from the pumped medium is equal to the displacement angle β=β.EFFECT: technical result achieved by a group of inventions consists in increasing the efficiency, life and reliability of the oil unit displacement pump.9 cl, 6 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 663 783 C1 (51) МПК F04C 11/00 (2006.01) F04D 13/12 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ...

Slipper sealing means for a dual acting pump

Vane pump, especially for hydraulic oil at a power assisted steering system, has grooves at the suction kidneys for an additional flow path to the pressure zone

The vane pump, with a rotor powered by a drive shaft which rotates within a lifting ring between two side plates, has radial slits within its peripheral surface for vanes with a radial sliding movement to move fluid from a suction zone to a pressure zone. The pressure zone and the suction zone are each respectively connected to at least one pressure kidney (14,15) and at least one suction kidney (18,19). A groove (26,27) under the vanes, at the suction kidneys, gives an additional flow path to the pressure zone.

Multi-stage automotive fuel pump

A multi-stage automotive fuel pump includes a casing 12 and motor 14 located within the casing for driving primary and secondary pumping sections, with the primary and secondary pumping sections sharing a common wall 22 which axially separates primary and secondary rotary pumping elements 18, 27 and which houses a fuel transfer passage 28 for moving fuel from the primary into the secondary pumping sections in a manner which avoids generation of turbulence and cavitation. The centre channel of the passage lies at an acute angle to the faces of the pumping elements 18, 27, preferably 25 - 30 DEG . <IMAGE>

Fuel pumping system

A fuel pumping system comprises a high pressure pump having a drive input, a drive gear driven for rotation, in use, by the drive input, an idler gear driven by the drive gear, and an output gear driven by the idler gear, wherein the output gear is arranged to drive a rotor of an electrical generator and the idler gear is arranged to drive a rotor of a low pressure pump.
