    • The invention relates to a vane cell pump having a rotor which is mounted in a pump housing and is driven by a shaft, a plurality of vane plates which are mounted radially displaceably in the outer circumference of said rotor, and an outer shell which surrounds the rotor and the vane plates and is arranged directly in the pump housing. The invention is based on the problem of developing a novel vane cell pump which does not require any novel vane materials or any novel vane geometries; and which vane cell pump, even in the case of a small, double-action vane cell pump, can already ensure optimum complete filling of the pump chambers in the rotational speed range from 0 rpm to 400 rpm, in the case of a simple structural design, simple inexpensive production and assembly, and which vane cell pump additionally at the same time always operates without maintenance and with high reliability and a high degree of efficiency. According to the invention, this problem is solved by a vane cell pump which is distinguished, in particular, by the fact that the vane movement in the lower rotational speed range is brought about by pins according to the invention, the guide needles (12), which are positively guided, are decoupled from the vane plates (5) and, during pressureless operation, are positively guided on both sides of the rotor (3) in the control grooves, the guide grooves (13), which are arranged according to the invention in the end side/sides of the pump housing (1) and/or in the pump-housing cover/covers (9) which is/are arranged on the end side of the pump housing (1).

    • A rotary pump (10) comprises a housing (20) having a first (21) and second fluid port (22) and an interior surface defining a cavity (24) in which a rotor (30; 230) is located, wherein the rotor comprises at least a surface recess (231a-231d) forming at least a fluid-conveying chamber (232a-232d) with the interior surface of the housing. The pump further comprises at least a resiliently deformable diaphragm (50; 226) providing part of the interior surface of the housing and being urged into contact with the surface of the rotor by the action of pressurising means acting on the rear surface of the resiliently deformable diaphragm. The pump further comprises one or a pair of flow channels (41a, 41b; 241a, 241b) associated with the resiliently deformable diaphragm extending longitudinally from opposite ends of the rotor. In embodiments where the pump comprises one flow channel (575), the flow channel is in fluid communication with the first fluid port and an aperture (595) opens from the interior surface of the housing to place the second fluid port in direct fluid flow communication with the fluid-conveying chamber. In embodiments where the pump comprises a pair of flow channels (241a, 241b), the pair of flow channels comprise a first flow channel in fluid communication with the first fluid port and closed to the second fluid port and a second flow channel closed to the first fluid port and in fluid communication with the second fluid port, with each flow channel being located at opposite sides of the diaphragm. Embodiments of the invention exhibit continuous fluid flow when in use.
