    摘要： A tip seal back-up member is disclosed for use in fluid apparatus of the scroll type, which member comprises a strip of material extending longitudinally in generally spiroidal configuration about a reference axis and having a preformed configuration such that its radially inner and outer edge portions are disposed axially with respect to each other. The strip of material comprises an elastic material such that as one of the edge portions is displaced axially toward the other, an opposing spring force is developed. In operation, the back-up member is disposed within a groove located in a tip surface of a wrap element in fluid apparatus of the scroll type, between a bottom wall of the groove and a tip seal. Preferably, the strip of material is generally flat between its radially inner and outer edge portions and is constructed from steel.

    摘要： A rolling thrust bearing for use in a scroll type positive fluid displacement apparatus is disclosed. In the invention, a plurality of ball bearings spaced apart in cavities formed in a bearing cage are operative to transmit an axial force between a supporting frame and an orbiting scroll member. The bearing cage rotates within a groove in which it is seated due to frictional forces between its flank surfaces and the sides of the groove. In a first embodiment, the diameter of the cavities is substantially larger than the diameter of the ball bearings, and the bearings are free to orbit within the cavities as the bearing cage rotates. In the second embodiment, the cavities are only slightly larger in diameter than the ball bearings, but the radial width of the bearing cage is substantially less than the width of the groove, and the bearing cage and the ball bearings together describe an epicycloidal path about the central axis of the bearing cage. In both embodiments, the ball bearings seated within the cavities contact adjacent bearing races over a constanty changing portion of their surface. This substantially extends the operational life of the thrust bearing.

    摘要： A variable flow rate expansion valve designed for in-line installation in a fluid conveying conduit such as between the high pressure condenser and lower pressure evaporator of a refrigeration system includes an integrally defined restrictor disc and a closure disc for controlling the flow of fluid through the valve. The restrictor disc has a first set of flow apertures and the closure disc a second set of flow apertures. The closure disc is rotatably coupled to the restrictor device in a plane parallel to the plane of the restrictor disc and perpendicular to refrigerant flow. A stepper motor is coupled to the closure disc through a linear actuator. Movement of the linear actuator causes the closure disc to rotate relative to the restrictor disc such that the flow apertures of the closure disc are selectively brought into and out of registry with the apertures of the restrictor disc.

    摘要： Inside the hermetic shell of a scroll compressor, a normally closed solenoid valve seats against the back side of a stationary scroll plate to close a discharge opening through the plate. A coil circuit that actuates the valve has an electrical resistance that increases with temperature. The temperature dependent resistance allows the coil circuit to also function as a discharge temperature sensor. Should the discharge gas over-heat, the compressor motor and the valve are de-energized in response to the resistance exceeding a predetermined limit. The closed valve prevents backflow from rapidly reversing the rotational direction of the compressor, which can be extremely noisy and damaging to the compressor. Both the valve and the compressor motor are energized at the same time, regardless of the compressor's direction of rotation. Should the compressor motor be inadvertently wired to operate in reverse, the solenoid valve still opens to prevent destructively low pressure from developing between the scroll plates.

    摘要： An air valve actuated by an electric motor has a cylindrical inlet section. The inlet section defines a seating surface upstream of which is a support grid. A backplate, upon which the actuating motor is mounted, is fixedly supported by a plurality of rods that extend downstream of the inlet section. A damper assembly includes a generally planar damper mounted for movement axially of the inlet section. The damper assembly includes a splined rod which extends upstream and into a cooperating spline in the support grid. A threaded spindle extends downstream of the damper plate through a cooperatively threaded motor-driven drive gear which is mounted for rotation on the backplate. Because a portion of the damper assembly is splined, the damper assembly cannot rotate and is driven axially within the valve by the rotation of the drive motor and drive gear. A strain sensing device is mounted on the valve such that the abutment of the damper with the inlet section seating surface, which causes a detectable strain to develop within the valve, is sensed immediately upon its occurrence. The strain signal from the sensor is used to control the de-energization of the motor so that the stalling of the motor as a result of its driving the damper into abutment with the inlet section seating surface is prevented while the development of a tight seal between the damper and its seating surface is assured.

    摘要： Oil management apparatus for a refrigeration chiller includes a housing mounted to the head wall of an oil supply tank. The housing defines a series of ports and internal flow passages in communication with a valve cavity. A valve spindle disposed in the cavity is configured and positionable such that a plurality of oil flow passages within the chiller are capable of being setup in order to accommodate various chiller lubrication needs including those as they relate to both chiller operation and maintenance. The combination of an integral housing and single valve eliminates a large number of individual valves and the need to connect those valves and various chiller lubrication components, such as an oil filter and oil pressure regulator, with individual sections of difficult to fabricate piping. As a result, the likelihood of error in the setup of a chiller lubrication system is significantly reduced.
