Abstract:
A coupling assembly for connecting two members is provided that includes a first nullmalenull member and a second nullfemalenull 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.
Abstract:
A coupling assembly for connecting two members is provided that includes a first "male" member and a second "female" member. The first member 12, 96 includes a release sleeve (244) moveably mounted thereon having a rigid release portion 208 and a flexible sealing portion 248. The second member 14 is integrated into an apparatus, such as a pump, and includes a duct therethrough for receiving the first member 103. Upon connection of the first and second members, the flexible sealing portion 248 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 244 that releases the male member 12, 96 from both a conventional female member 103 and an integral female member 14.
Abstract:
A coupling assembly (520) is disclosed that includes a first member (522) and a second member (524) having a receiving portion (570) sized to receive the first member (522). A retaining formation (544) is provided on one of the first and second members (522, 524). The retaining formation (544) includes a ramp (546) and two or more grooves (537), wherein each groove (537) is at least partially defined by converging surfaces (539, 541). A locking member (590) is moveably secured in a cavity (574) in the other of the first and second members (522, 524). The locking member (590) is configured to be moved in a first radial direction by the ramp (546) upon movement of the first member (522) into the second member (524). The locking member (590) is also biased in a second radial direction opposite the first radial direction into a groove (537) in the retaining formation (544) to become positioned between a converging surface (541) on the retaining formation (544) and the cavity (574) upon further movement of the first member (522) into the receiving portion (570) of the second member (524), and may be progressively received in additional grooves (537) on the retaining formation (544) if the first member (522) is further inserted into the second member (524).
Abstract:
The present invention relates to a mounting stop at axially displaceable male-female couplings to prevent involuntary release of the coupling, whereby it comprises a recess (2) arranged to be placed in a first position around a shaft (32) and to be displaceable radially sidewise above said shaft (32) to a second position, and that it comprises at least one stop lug (6, 7; 9; 10) arranged, in said first position to be applied into a groove (34) and thereby to prevent an axial displacement of said male-female coupling parts towards each other, as well as a male part (32) present in such a coupling.
Abstract:
Fittings (10) of this invention generally comprise a body (12) having a substantially hollow transport passage (14) that extends between a body first end (16) and a body second end (18). Each of the fitting body ends (16,18) are adapted to accommodate attachment with respective fluid handling devices. The fitting (10) includes a hexagonal outside surface (32) portion for grasping and rotating the fitting (10). An interlocking attachment member (24) is disposed along an outside surface of the fitting body (12) and is adapted to form an interlocking attachment with a complementary member of a fluid handling device when the fitting (10) is connected thereto. In an example embodiment, the interlocking attachment member (24) comprises a plurality of rachet teeth (26) that are configured to register with a complementary fluid handling device member. The fitting body first end (16) includes a tongue (22) that projects axially a distance therefrom that is sized and shaped to provide an interference fit within a groove disposed within a fluid handling device opening. The tongue-in-groove attachment provides a leak-tight seal between the fitting (10) and the fluid handling device.
