Abstract: A coupling device for releasably interconnecting conduit elements includes two coupling members, each having a central opening therethrough. A tapered pocket is defined in one coupling member to act as a seat for slidingly receiving the other coupling member, which is in the form of a wedge-like element. An alignment mechanism ensures complete engagement between the two coupling members. Two annular grooves are disposed opposite each other about the central openings of the respective coupling members. A gasket is disposed in one of the grooves for engaging the opposite groove when the coupling members are fully interengaged. The gasket has a first annular portion of a compressible resilient material for positioning in one annular groove, and a second annular portion extending from the first annular portion, of a less compressible material, for compression into the first annular gasket portion as the coupling members are being interengaged.

Abstract: A fluid strainer device is disclosed. The device includes a housing which defines an open chamber, the chamber having both at least one fluid input port and at least one fluid outlet port. A plurality of spaced strainer baskets are disposed within the chamber. Each basket has a pair of spaced perforated side panels, a perforated rear panel, a perforated top panel and an open front portion in fluid communication with the chamber fluid input port. Finally, each strainer basket is aligned within the chamber for fluid flow from the chamber input port into the basket's open front portion and out through the perforations thereof to filter debris from the fluid while preventing substantial fluid pressure drop between the input and outlet ports substantially independent of debris buildup within the baskets.
