摘要： A restrictor for limiting the volume of fluid flowing from an automotive hose into a heat exchanging device in an automotive heating or air-conditioning system is disclosed. The restrictor includes a generally cylindrical, hollow body disposed in the hose and a flow limiting washer disposed in the body. The body includes an annular wall having a stepped region of reduced cross-sectional area which receives a hose clamp therein to prevent sliding and rotation of the restrictor within the hose.

摘要： A tubular coupling is provided having first and second tubular elements. An annular cage is fixedly mounted on the outer surface of a first section of the first tubular element for defining a chamber with the first section for housing a garter spring. The chamber has an annular passage through which a flared end part extending from a first portion of the second tubular element passes during assembly of the first and second tubular elements to permit the garter spring to pass over the flared end part and contract about the first portion for securing the tubular elements in assembly. An expander ring is provided for expanding and centering the garter spring prior to assembly. Further provided are O-rings retained on the outer surface of the first tubular element for sealing the first tubular element to the second tubular element. The O-rings engage with the second tubular element just before the first and second tubular elements are secured in assembly.

摘要： An accumulator with an inlet port comprising a deflector for use in an air conditioning or refrigeration system, and a method for use thereof are disclosed. In operation, the accumulator is provided between the evaporator and compressor of an air conditioning or refrigeration system. Vaporized refrigerant is conveyed from the evaporator into the accumulator through an inlet port having a deflector. The deflector deflects the refrigerant from the inlet port in a spray pattern to reduce the velocity of the refrigerant thereby avoiding turbulence in the accumulator. In another embodiment, a vapor conduit inside the accumulator for conveying refrigerant to an outlet port has an open vapor inlet end with chamfered cut edges pointing away from the inlet port to avoid liquid from splashing into the vapor conduit.

摘要： A coupling and methods for assembling and using the coupling for connecting a hose with a tube, pipe or other hose in an automotive refrigerant system. The coupling comprises a connector member connected to a tube, pipe or hose, the connector member having at least one circumferential groove into which at least one sealing member is disposed. A hose is fitted over the connector member and covers the sealing member. A collar is disposed over the hose and the at least one sealing member and is deformed such that the hose is brought into engagement with the at least one sealing member and the at least one sealing member and hose occupy substantially 100% of the volume of the at least one circumferential groove.
