摘要： A pump assembly comprises an inlet, an outlet and a housing having an inlet aperture in fluid connection with the inlet, and an outlet aperture in fluid connection with the outlet. A rotor located within the housing is shaped to form with an interior surface of the housing a chamber. On rotation of the rotor, the chamber conveys fluid from the inlet aperture to the outlet aperture. The housing carries a seal located in the inlet and urged into contact with the rotor to prevent the passage of fluid past the rotor from the outlet to the inlet. Center lines of the inlet and the outlet are parallel to one another. The outlet can be formed by linear movement of a mold core.

摘要： A method of manufacturing a scroll member for a compression mechanism installed in a scroll compressor includes a casting step and a cutting step. An iron casting is formed in the casting step, which includes a spiraling part. The iron casting obtained in the casting step is cut during the cutting step in order to obtain a final shape of the scroll member. The iron casting may include a fixed part having a central portion with a first axial thickness and an external periphery portion with a second axial thickness larger than the first axial thickness before the cutting step. A dimension of a specified portion of the spiraling part may be larger before the cutting step is performed than after the cutting step is performed, with the specified portion preferably disposed toward an external periphery of the spiraling part.

摘要： This invention relates to a Dry Running Flexible Impeller Pump and Method of Manufacture designed to provide a flexible impeller pump capable of being run dry for extended periods of time without damage. The pump's components are comprised of low friction materials limiting the heat of friction created by the impeller in use. The impeller is cast of pre-molding silicone substrate containing a quantity of mold release that will not prevent the deposition of a low friction compound coating on the surface of the impeller in a mold that is treated with a low friction industrial coating. Once the impeller is removed from the mold it is solvent cleaned, vacuum baked at a temperature high enough to drive off residual traces of mold release or compounds used to maintain the silicone substrate in suspension, and then coated with a polymer of Poly Para Xylylene by vacuum deposition.

摘要： A method of making a pump housing that is net-molded and immediately assumes its final shape and design specification without requiring more than de minimis secondary machining processes. The method utilizes molds and cores configured such that none of the fluid ports of the housing produced using the molds and cores have any intersecting geometry. The net-molded pump housing may also include a cross-tube insert providing flow communication between a fluid inlet port and a pressure relief port.
