Trochoid oil pump

A trochoid oil pump, which enables the endurance to be increased and the reduction of discharge pulsations and noise to be achieved, and in which those results can be realized with a very simple structure. An interdental space constituted by an inner rotor and an outer rotor having trochoid tooth profile or substantially trochoid tooth profile starts a compression stroke in the location of a partition section between an intake port and a discharge portion, and a linking gap L is composed by the interdental space and a preceding adjacent interdental space realized in a discharge stroke. The linking gap expands gradually from the start of compression stroke to the discharge stroke.

PUMP, ESPECIALLY FOR CONVEYING CONSTRUCTION MATERIALS

A pump is comprised of a housing within which a rotary piston is rotatably mounted, to define therebetween an annular conveying channel between an inlet port and an outlet port. Annular sealing rings between the piston and housing seal the conveying channel at the periphery of the piston. A stopper extends into the conveying channel in the back flow path, and sealing elements are provided to seal the entire cross section of the back flow paths. Radially movable slides on the piston are resiliently urged into the conveying channel, the radial position thereof being controlled by a cam surface in the housing. The slides are urged radially outwardly by springs, and seals are provided on the piston for sealingly guiding the piston in the radial direction.

Rotary fluid-displacement assembly

A rotary fluid-displacement assembly having a housing and a rotor positioned within an internal cavity of the housing. The rotor being configured to rotate about a rotor axis of rotation eccentric to a housing longitudinal axis. A gate is also provided that is slidably mounted therewith the rotor and movable axially about and between a first position, in which a distal end of the gate is positioned at a first distance from the peripheral surface of the rotor, and a second position, in which the distal end of the gate is positioned at a second distance from the peripheral surface of the rotor. The distal end of the gate being constrained to be spaced proximate from the inner wall surface of the housing as the rotor rotates about the rotor axis of rotation.

Compressor

A compressor is provided that eliminates sliding contacts between a cylinder and a roller to minimize mixing of lubricating oil into a refrigerant. The compressor includes a hermetic container that stores the lubricating oil at a lower portion thereof; a stator mounted within the hermetic container; a cylinder type rotor that rotates within the stator by a rotating electromagnetic field of the stator and defines a compression chamber therein; a roller that rotates and compresses the refrigerant by a rotational force transferred from the rotor; a rotational shaft integrally formed with the roller; a vane that divides the compression chamber into suction and compression regions and transfers the rotational force to the roller; and oil feed passages provided in the rotational shaft and the roller to feed the lubricating oil to areas where two or more members are slidingly engaged with one another within the compression chamber.
