摘要： A coupling assembly for connecting two members is provided that includes a first “male” member and a second “female” member. The first member includes a release sleeve moveably mounted thereon having a rigid release portion and a flexible sealing portion. The second member is integrated into an apparatus, such as a pump, and includes a duct therethrough for receiving the first member. Upon connection of the first and second members, the flexible sealing portion sealingly engages a recessed seat portion of the second member to substantially inhibit the ingression of contaminates into the duct when the first and second members are connected. The foregoing coupling assembly is advantageous because it allows the second member to be formed directly into an apparatus. In other embodiments, the coupling assembly provides an improved release sleeve that releases the male member from both a conventional female member and an integral female member.

摘要： A coupling assembly is disclosed that includes a first member and a second member having a receiving portion sized to receive the first member. A retaining formation is provided on one of the first and second members. The retaining formation includes a ramp and two or more grooves, wherein each groove is at least partially defined by converging surfaces. A locking member is moveably secured in a cavity in the other of the first and second members. The locking member is configured to be moved in a first radial direction by the ramp upon movement of the first member into the second member. The locking member is also biased in a second radial direction opposite the first radial direction into a groove in the retaining formation to become positioned between a converging surface on the retaining formation and the cavity upon further movement of the first member into the receiving portion of the second member, and may be progressively received in additional grooves on the retaining formation if the first member is further inserted into the second member.

摘要： A female coupling member includes a body portion, a slideable sleeve positioned in the body portion and an axially extending stem valve sealingly engageable with the sleeve. Axial movement of the sleeve relative to the stem valve opens the female coupling member to the flow of fluid. The stem valve is provided with a cavity sized to receive a protruding nose of a male member to be attached thereto. The slideable sleeve and the stem valve are designed to receive the male coupling member including its flat insertion end and protruding nose with minimal air inclusion and minimal fluid loss upon disengagement.

摘要： A coupling assembly for connecting two members is provided that includes a first “male” member and a second “female” member. The first member includes a release sleeve moveably mounted thereon having a rigid release portion and a flexible sealing portion. The second member comprises at least one of an integral coupling member integrated into an apparatus, such as a pump, and an independent coupling member. Upon connection of the first and second members, the flexible sealing portion sealingly engages a mating surface on the second member to substantially inhibit the entry of contamination into an area between the first and second members when connected. The present invention provides an improved release sleeve that releases the male member from both an independent female member and an integral female member.

摘要： A manually adjustable service adapter includes a manually adjustable actuation shaft for opening the valve of a charging port of a refrigeration system to permit the charging of refrigerant into such system. Actuation of such charging port results from an axially movable shaft in combination with one of two internal, axially slideable sleeves. The axially movable actuation shaft is manually adjustable by a rotatable knob which causes it to move axially but non-rotatably. Such axial movement of the shaft along with restriction of movement of one slideable sleeve upon abutment against the other slidable sleeve when the adapter is engaged to the charging port, opens the seal between the shaft and such one slideable sleeve while movement of the shaft with its end engaged to the valve of the charging port, opens such valve. Means are provided for preventing rotational movement of the axially movable shaft.
