Abstract: An energy absorbing airbag system includes one or more vent valve assemblies for controlling the release of airbag inflation gases to maintain inflation gas pressure within an airbag at a substantially constant pressure during a ride-down of an energy absorbing event. Each vent valve assembly includes a cantilever spring that is flat in an unstressed condition and that has a free end portion. The cantilever spring is secured to an exterior surface of the airbag housing and flexed to cause the second free end portion of the cantilever spring to be pressed, with a preset force, against a vent port or a closure covering the vent port to seal the vent port until inflation gas pressure within the airbag reaches a preselected value determined by the preset force whereupon the free end portion of the cantilever spring is lifted from the vent port by the inflation gases within the airbag to vent the inflation gases from within the airbag.

Abstract: A compact liquid discharge regulator is provided at low cost by arranging a channel spirally formed in the surf ace of a passage forming member. The surface of the passage forming member is brought into close contact with the inner surface of a housing part, and the channel functions as a liquid passage. In this construction, the sectional form and length of the channel can be formed at high precision in accordance with the design. Therefore, a desired pipe loss is obtainable only by designing in advance the sectional form and length of the channel so as to correspond to the pipe loss. Particularly, with injection molding, mass production of a passage forming member of identical pipe loss can be effected merely by preparing a mold corresponding to the pipe loss, thus leading to a considerable reduction in the manufacturing cost of the discharge regulator.

Abstract: The present invention relates to a multiple-purposed air valve component for air mattress. The air valve is designed mainly for rapid injection and release of air for the air mattress. This invention can be incorporated with electric exhaust (intake) fan for rapid injection and release of air. In particular, the present invention is the first device of which the air valve can be opened and closed by winding, thereby ensures the correct motion. When it is switched to the release position, the air inside the mattress will be released rapidly to facilitate the execution of CPR. The additional function of automatic pressure release makes this device a practical and innovating one.

Abstract: A check valve for use in a filler pipe of a motor-vehicle fuel system, having a housing fixed in the interior of the pipe and a movably mounted flap closure which is opened by the flow of fuel through the filler pipe to the fuel tank, and closes again automatically when fueling stops. According to the invention, a configuration that is particularly favorable in terms of flow dynamics is provided wherein the flap closure comprises two valve flaps which are movably mounted jointly in the region of the center of the housing.

Abstract: A fire department connection (“FDC”) and a check valve in one. FDC saves labor and time when compared to the current FDC, because with current FDC, one has to install a check valve and then install the FDC. The new FDC is a one-step process. FDC is equipped with swivels which don't allow debris, garbage or trash to be deposited in the FDC and this makes FDC debris proof. FDC allows back flushing test to be performed by removing the cap and reversing the FDC. FDC comes with three different styles of outlets which are grooved, flange, and threaded. This gives the consumers more selections to suit their needs. Current FDC's come only with one style of outlet, which is threaded outlet.

Abstract: Addow's FDC is different from current FDCs, because it is a FDC and a check valve in one. Addow's FDC saves labor and time when compared to the current FDC, because with current FDC, one has to install a check valve and then install the FDC. With Addow's FDC, it is a one step process. Addow's FDC is equipped with swivels which don't allow debris, garbage or trash to be deposited in the FDC and this makes Addow's FDC debris proof. Addow's FDC allows back flushing test to be performed by removing the 4 inch cap and reversing the FDC. Addow's FDC, unlike current FDCs, comes with three different styles of outlets, which are grooved, flange, and threaded. This gives the consumers more selections to suit their needs. Current FDCs come only with one style of outlet, which is threaded outlet.

Abstract: A compressor assembly includes a shell which defines a discharge chamber. A discharge valve assembly is attached to the shell in communication with the discharge chamber. The discharge valve assembly includes a stamped or coined valve seat, a drawn tubular element and a stamped valve member. The stamping, drawing and coining operations used to manufacture the discharge valve assembly significantly reduce the manufacturing costs for the discharge valve assembly.
