    摘要： The present invention recites a downhole motor and method of manufacture wherein a mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator is provided. A flexible sleeve is provided over the mandrel and the flexible sleeve and the mandrel are provided into a mold. Additionally, a reinforcing material is introduced into the mold to fill space between the flexible sleeve and the mold. Said material is then solidified to bond the reinforcing material and the flexible sleeve. The solidified reinforcing material and flexible sleeve are then removed from the mold such that a stator insert is fabricated.

    摘要： Implementations of the present invention comprise a rotor assembly for use in a rotary compressor. The rotor assembly includes a shaft, a pair of end plates, an input shaft, and a rotor. The rotor can be positioned between the pair of endplates. At least two of these components can be machined or formed as an integral unit, to increase the geometrical precision and integrity of the rotor assembly. For example, the rotor and input shaft can be formed integrally; alternatively, one of the endplates and the input shaft can be formed integrally. A pair of liners can be provided and positioned between the endplates and the rotor to increase sliding and/or sealing performance against other components of the rotary compressor, such as a gate positioned in a bore of the rotor.

    摘要： A rotary compressor 1 includes a pair of closing members 11 and 12 that close axial front and rear opening portions of a cylinder 5, and a rotor 6 that is accommodated within the cylinder 5 and rotated by a motor.Concave portions 11C and 12C having the same depth are respectively formed in inner wall surfaces 11A and 12A of the closing members 11 and 12, and the concave portions 11C and 12C are filled with synthetic resin coatings 22. Accordingly, the surfaces of the synthetic resin coatings 22 are flush with the inner wall surfaces 11A and 12A located outwardly adjacent thereto (a left side in the drawing).The rotary compressor 1 which can prevent a seizure on end surfaces 6A and 6B of the rotor 6, and can be manufactured at low cost can be thereby provided.

    摘要： A system for monitoring wear of pump casing liners is disclosed. The system may include a wear sensor disposed in proximity to the pump casing liner so that the sensor wears at substantially the same rate as the lining. The wear sensor may include a plurality of circuit loops having different lengths. As the pump casing liner and the sensor wear during use, the plurality of circuit loops are sequentially breached. A control system monitors the signals from the plurality of circuit loops to develop liner wear information. This information is employed to signal a user when one or more predetermined wear thresholds are exceeded. Other embodiments are described and claimed.

    摘要： A hydraulic pump of the intermeshing spur gear type has a onepiece liner for the gear cavity in the body. The liner is a Cshaped piece of resilient metal coated with bearing material and in its free state, is larger than the cavity and requires elastic compression to be inserted therein. The inlet passage is formed with three branches for improved filling at high speeds.

    摘要： A pump includes a housings and a rotor capable of rotating within the housing. The rotor engages an interior surface of the housing in use, with at least two radially-inward shaped surfaces on the rotor forming respective chambers with the interior surface. In use, the chambers transport fluid from an inlet in the housing to an outlet in the housing as the rotor rotates. A seal provided between the inlet and the outlet will engage each of the shaped surfaces to prevent fluid passing from the outlet to the inlet as each shaped surface travels from the outlet to the inlet. The rotor includes a surface portion extending axially and circumferentially between respective edges of the shaped surfaces. On planes normal to an axis of rotation of the rotor, the surface portion of the rotor has a greater curvature than that of the interior surface of the housing.
