Abstract: A releasable coupling assembly for connecting two members is provided that includes a first member having an exterior surface with a receiving portion and a second member having a hose adapter and a sleeve valve positioned within the adapter. The sleeve valve is in slidable communication with the adapter and includes at least one socket aperture that includes a mating ball that contacts at least one longitudinal groove in the adapter that includes a first and expanded radial portion. When the members are secured together, the ball of the sleeve valve is retained in the receiving formation of the first member by the first radial portion of the longitudinal groove of the hose adapter.

Abstract: A noise suppressor device for absorbing pulsating fluids is disclosed. A noise suppressor device has a housing which defines an axially extending bore. A resilient bladder is coaxially positioned in the bore. A spool assembly is coaxially positioned within the bladder. The spool assembly has an inner spool layer and an outer spool layer which coaxially surrounds the inner spool layer. The inner spool layer and outer spool layers each define a plurality of perforations extending therethrough. The perforations in the outer spool layer are offset from the perforations in the inner spool layer such that a direct line of sight through the first perforations and second perforations is prevented.

Abstract: A coupling utilizes a male member having an internal poppet valve yieldingly urged to a closed position and an external ball retention sleeve yieldingly urged toward its connector end engageable with a female member. The female member has an internal poppet valve yieldingly urged to a closed position and a forward connector end wall section having a plurality of apertures in which are positioned balls for engaging an annular groove of the male member. The female member includes a retainer for preventing the balls from falling outwardly from the apertures.

Abstract: An improved marine drain valve is disclosed. The valve includes a valve barrel having an intake opening and a discharge opening. A fluid passageway extends between the openings. A valve adaptor body surrounds the valve barrel and a torsion-compression spring is positioned between and attached to the valve barrel and the adaptor body. A vent passageway is defined by the valve for venting a reservoir to which the valve is attached. An operating pin extends outwardly from the valve barrel and is received for movement in a configured slot defined by the adaptor body. The slot has a first leg parallel to the valve barrel and a second leg extending perpendicular to the first leg. The spring urges the valve toward a nonoperating or locked position. To operate the marine drain valve, a user rotates the operating pin and forces it upwardly into the first leg of the slot thereby opening the valve. Upon release, the spring returns the operating pin to the locked position.
