摘要： A pump assembly comprising a housing, a support frame that can be attached to the housing, and a rotor that can rotate within the housing. The housing consists of resilient material and comprises an interior surface, an inlet portion including an inlet for fluid, an outlet portion including an outlet for the fluid, and a diaphragm portion. A housing-engaging surface area of the rotor will form a sealing interference contact with the interior surface, and a chamber-forming surface area of the rotor disposed radially inward from the housing-engaging surface area will form a chamber with the interior surface. When the rotor rotates within the housing as in use, the chamber can convey fluid from the inlet portion to the outlet portion. The diaphragm portion will bear against the chamber-forming surface as the chamber-forming surface travels from the outlet to the inlet, to prevent fluid passing from the outlet to the inlet and to expel the fluid from the chamber through the outlet portion. The support frame will be attached to spaced-apart portions of the housing, and will be sufficiently stiff to counter-balance the torque applied to the housing by the rotor.

摘要： A pump comprises a housing (10) and a rotor (11) that rotates in the housing. The housing (10) has a fluid inlet (14) and a fluid outlet (15). The rotor (11) includes two shaped surface (21, 22; 50a, 50b, 50c) radially inwardly of the housing (10) and forming with the interior surface of the housing respective chambers (23, 24; 51a, 51b, 51c) for conveying fluid from the inlet (14) to the outlet (15) on rotation of the rotor (11). A seal (12; 56) is provided between the outlet (15) and the inlet to engage the shaped surfaces (23, 24; 50a, 50b, 50c)) to prevent the passage of fluid from the outlet (15) to the inlet (14) as each shaped surface (23, 24; 50a, 50b, 50c) travels from the outlet (15) to the inlet (14). The shape of the surfaces (21, 22; 50a, 50b, 50c) provides an optimised volume for the chambers (23, 24; 51a, 51b, 51c) and the seal (12; 56) is urged into contact with the rotor (1 1) by spring arrangements (13, 39, 41, 59) that provide an even force along the axial length of surfaces (21, 22).

摘要： An exemplary pump includes a pump housing defining a pump cavity, a movable pumping member situated in the pump cavity, and at least one pressure-absorbing member located inside the pump housing. The housing also has an inlet and an outlet, and includes at least one interior non-wearing location that contacts liquid in the pump housing when the pump housing is primed with the liquid. The movable pumping member, when driven to move, urges flow of the liquid from the inlet through the pump cavity to the outlet. The at least one pressure-absorbing member is located inside the pump housing at the non-wearing location and contacts the liquid. The pressure-absorbing member has a compliant property to exhibit a volumetric compression when subjected to a pressure increase in the liquid contacting the pressure-absorbing member, the volumetric compression being sufficient to alleviate at least a portion of the pressure increase.

摘要： The present invention is a fluid handling device such as a helicoidal pump or motor having a stator (8) formed by an elastomer material in which a plurality of fibers (22-25; 30-32) are encapsulated. Preferably, the fibers form a network of interlaced fibers extending in two or more directions. The fiber network preferably forms multiple layers of flexible fabric encircling the stator axis. In addition, a group of fibers (26) can extend radially through the fabric layers. The fibers increase the strength, the stiffness of the elastomer, and also create heat conduction paths that improve the heat transfer within the stator core, thereby preventing overheating of the elastomer.

摘要： A heat pump system 160 contains a hydristor pump/motor 162 in fluid and thermodynamic communication with a first heat exchanger 172 communicating with a relatively warm reservoir 174, and a second heat exchanger 176 thermodynamically communicating with a relatively cold reservoir 178, whereby the hydristor 162 and the first and second heat exchangers 172 and 176 are integral to and in fluid communication with a closed compressible fluid loop 164. A Stirling engine 178a or a home heating system or any other cold reservoir may, for example, utilize heat transferred from the second heat exchanger 176 thereby providing a reduction in energy usage and costs heretofore unrealized

摘要： A pump is formed by a housing (10) having a fluid inlet (11) and a fluid outlet (12) and containing a rotor (15) forming with the housing (10) chambers (17a, 17b) that, on rotation of the rotor (15) by a drive, convey fluid from the inlet (11) to the outlet (12) to pump the fluid. A seal assembly (14) is arranged between the outlet (12) and the inlet (11). The seal assembly (14) includes a membrane (21) that contacts the rotor (15) and a flexible resilient spring member (22, 28, 35, 37, 40) that provides a force urging the membrane (21) against the rotor (15). The spring member (22, 28, 35, 37, 40) thus, on rotation of the rotor (15), moves radially relative to the axis of rotation of the rotor (15) and is arranged to provide a force on the rotor (15) via the membrane (21) that is constant and a minimum to maintain a seal between the rotor (15) and the seal (14) for a given outlet pressure of the pumped fluid.

摘要： A pump comprises a housing (10, 210, 300, 410), the housing having an interior defining a rotor path (10, 210, 300, 410), an inlet (111, 211) formed in the housing (10, 210, 300, 410) at a first position on said rotor path, an outlet (12, 212) formed in the housing (10, 210, 300, 410) at a second position on said rotor path spaced from said first position. A rotor (15, 315, 350, 415) is rotatable in the housing. At least one first surface is formed on the rotor (15, 315, 350, 415) and seals against said rotor path of the housing (10, 210, 300, 410). At least one second surface is formed on said rotor (15, 315, 350, 415) circumferentially spaced from said first surface and forms a chamber with the rotor path that travels around said rotor path on rotation of the rotor (15, 315 350, 415) to convey fluid around the housing (10, 210, 300, 410) from the inlet (111, 211) to the outlet (12, 212). A resilient seal (114, 214) is formed in one piece with the housing (10, 210, 300, 410), located on said rotor path and so extends between the outlet (12, 212) and the inlet (111, 211) in the direction of rotation of said rotor (15, 315, 350, 415) that the first rotor surface seals with, and resiliently deforms, the seal (114, 214), as the rotor (15, 315, 350, 415) rotates around the rotor path within the housing to prevent fluid flow from said outlet (12, 212) to said inlet (111, 211) past the seal. A passage (101, 201) may be provided to supply fluid to an under surface of the seal (114, 214) at a pressure that acts to urge the seal (114, 214) against the rotor (15, 315, 350, 415). The rotor path may be frustoconical with the first surface of the rotor (15, 315, 350, 415) also being frustoconical and being a mating fit with the rotor path.
