摘要： A quick connect fitting for connecting a plastic or metallic tube (42) in a fluid circuit includes a fitting body (20) having an interior cavity (22) opening to the exterior of the body (20) via a generally circular port (36). A peripheral step (48) is located in the port (36) and an O-ring (50) is abutted against the step (48). A washer (52) is located in the port (36) and has a central opening (54) slightly larger than the outer dimension of the plastic or metallic tube (42). A peripheral flange (56) is disposed on the washer is directed away from the O-ring (50). A retaining ring (62) is disposed in the port (36) and nominally abuts the flange (56). The retaining ring (62) has a central opening (64) substantially greater than the outer dimension with a plurality of resilient, radially inwardly directed, angularly spaced fingers (66). The radially inner ends (70) of the fingers define a tube passage area (68) and are provided with cutting surfaces (72) for digging into the outer surface of the plastic or metallic tube (42). A lock member having a central opening (100) for receiving the plastic or metallic tube (42) is provided and is secured in the port (36) against the retaining ring (62) and abuts the fingers (66) so that they can only deflect into and out of the washer and not toward the member to provide positive retention of the tube (42).

摘要： A pole piece (14a) of the movable core (12) moves in an air gap (25a) between external (61) and internal (16) pole pieces. A pole flange (14b) of the same core (12) moves in an air gap (25b) between a portion (30b) of the external pole piece (61) and a magnetic lobe (36) which is in contact with this latter. A permanent return magnet (17) is disposed between the internal (16) and external (61) pole pieces. The magnet (17), the internal pole piece (16) andthe lobe (36) are maintained in a cage (60) of plastic material snap fastened by hooks (78, 80) on the external pole piece (61). Three cross pieces (75, 76, 77) connectingtwo longitudinal walls of the cage to each other, suitably separate the different magnetic components. The force of attraction of the magnet (17) prevents the pole pieces (16, 61) from leaving it.

摘要： Start up difficulties in gas compression systems due to undersized motors and/or low voltage conditions are avoided in a system including an electrically operated compressor (10, 36) including a compression chamber (34), a compressed gas reservoir (20) connected to the compression chamber (34) to receive gas therefrom, a pressure control switch (16) associated with the reservoir (20) and operable to control operation of the compressor (10, 36) in response to the pressure level of gas within the reservoir (20), and an unloader valve (42) connected to the compression chamber (34) and operable by the switch (16) by a valve construction including a valve body (50), an inlet (62) to the valve body (50) and in fluid communication with the compression chamber (34), and an outlet (68) from the valve body (50) to the ambient. A relatively large first passage (52) is located in the valve body (50) and extends between the inlet (62) and the outlet (68). A first valve seat (70) is located in the passage (52) and a first relatively large valve member (80) is movable within the passage (52) on the inlet side of the seat (70) and is operable to close against the seat (70). A second passage (88) is located within the valve (42) in bypass relation to the valve seat (70) and a second valve seat (90) is located in the passage (88). A second, relatively small valve (92) is movable in the second passage (88) and closable against the second valve seat (90) and includes an operator (116) extending exteriorly of the valve body (50) and connected to the second valve member (92) for operation via the pressure switch (16).
