摘要： A rotary fluid pump or compressor having a pair of flexible diaphragm type sealing plates which are clamped on opposite ends of a stator housing by end heads to form a cylindrical pump cavity and to be pressed onto the opposite end faces of a rotor driven within the pump cavity so as to provide sealing between the suction, compression and delivery chambers. Each of the sealing plates comprises a flat flange portion clamped between the end faces of the stator housing and the end head and a substantially cone shaped portion extending radially inwardly from the flat flange portion to be pressed onto the end face of the rotor and substantially coinciding at its apex with the axis of the rotor.

摘要： In a vane type rotary fluid pump or compressor, a plurality of vanes are slidably fitted in the body of a rotor at an angle with a radial plane passing through the axial center line of the rotor to move radially outwardly from the rotor in a direction opposite to the direction of rotation of the rotor. Each tip of the vanes is provided with a flat surface frictionally guided by a cylindrical inner wall of a stator housing and a taper surface extending from the front end of the flat surface toward the direction of rotation of the rotor. The flat surface of the vane has a predetermined width sealingly in contact with the inner wall of the stator housing.

摘要： A rotary fluid pump of a non-lubrication type having a pump cavity formed within a cylindrical stator housing and a pair of recessed end head assembles. A drive shaft is eccentrically journalled in the end heads with a rotor mounted thereon with vanes slidably disposed in radial grooves in the rotor. A pair of sealing plates disposed between the ends of the stator having and the end heads divide the pump cavity into a pair of end chambers and an intermediate rotor chamber. An outlet port provides fluid communication between the rotor chamber and a discharge hole in one of the end chambers so that fluid passage for discharge to the atmosphere is provided through the rotor chamber, outlet port, end chamber and discharge hole.

摘要： A dry rotary fluid pump or compressor includes a rotor eccentrically supported in a rotor chamber generally defined by a stator housing and two end heads. Two side plates each interposed between the housing and each of the end heads form end chambers between the respective side plates and end heads. The end chambers are supplied with a pressure higher than that of the rotor chamber so as to bring the side plates into close contact with opposite side faces of the rotor. The side plates are formed of a material having an abrasion resistance higher than that of at least the opposite side faces of the rotor.

摘要： A rotary fluid pump having a rotor with carbon vanes disposed in a rotor chamber. A cylindrical aluminum sleeve is force fitted into a mating arrangement with the inner peripheral surface of the rotor housing. The aluminum sleeve reduces the friction between the housing and the vanes. The sleeve may be of the same axial length or shorter than the rotor housing. If it is equal end seal plates are employed to provide the necessary expansion gap or end washers are employed at the housing to increase the effective axial length.

摘要： A rotary fluid pump has a stator housing with a generally cylindrical cavity extending therethrough and a pair of recessed end heads assembled at opposite ends of the housing to form a pump cavity therewith. A drive shaft is journalled in the end heads by bearings and extending eccentrically into the interior of the pump cavity and a rotor is mounted on the drive shaft within the pump cavity. A pair of sealing plates of different thickness are individually disposed between the ends of the stator housing and the end heads to divide the pump cavity into a pair of end chambers defined by the end head recesses and the plates and an intermediate rotor chamber defined by the plates. A plurality of vanes are slidably disposed in an equal plurality of grooves radially formed in the rotor. The drive shaft is constrained to prevent axial displacement by stoppers, washers or a combination thereof mounted on the shaft and contacting bearings that support the shaft. The bearings are fixed to one end head.
