Abstract: In-line flow regulator for use in hydraulic flow systems is presented using a fixed size orifice which may be manually adjustable by blocking off a part of the orifice to provide an exact rate of flow in the regulated flow direction and which otherwise provides a free flow in the reverse direction.

Abstract: A valve assembly providing a disconnectable coupling for a split system air conditioner including an indoor unit and an outdoor unit joined by connecting tubing to complete the sealed refrigerant system. The present valve is effective in providing a disconnect system between a unit and the connecting tubing. The valve is activated by an electric coil that is applied to the valve only during the disconnecting procedure.

Abstract: A valve includes generally cylindrical sleeve means and a valve member reciprocally mounted within it. There is an inlet and an outlet in the sleeve means with movement of the valve member controlling the flow of water between said inlet and outlet. A flexible sleeve is positioned within the sleeve means and between the inlet and outlet. The flexible sleeve and valve member have cooperating surfaces forming a closure between the inlet and outlet.

Abstract: A replacement valve stem assembly for a faucet in the form of an internally and externally threaded sleeve extending through and secured by nuts to the faucet cap and a threaded valve stem engaging the internal threads of the sleeve and having a valve washer secured to the inner end thereof and a faucet handle secured to the outer end thereof.

Abstract: The filling machine has a rotary tank containing the liquid, an annular channel surrounding the tank and containing gas having a lower pressure than the gas in the tank but higher than the atmospheric pressure, a filling unit adapted for sealing the container to be filled and including a filling pipe communicating with the interior of the tank and projecting into the container to be filled, a pressure control space communicating with the interior of the container around the filling pipe and connectable via a first control valve to the outer atmosphere, and further connectable via a second control valve to the annular channel, the second control valve being opened mechanically in response to the angular position of the rotary liquid tank and in addition being controlled during its open position by a separate timing device that closes the second valve if the mechanical control exceeds a predetermined time.

Abstract: A valve actuator and a pilot assembly responsive to control fluid pressure for moving an operative means of a valve. The actuator has a housing defining a cylindrical bore therethrough and a shaft is carried in the housing which is engagable with the operative means. A piston is carried by one of the shaft and the housing and is sealingly slidable along the other of the shaft and the housing and is longitudinally movable within the cylindrical bore. A plurality of piston chambers are companionly associated with the piston and is responsive to control of source fluid pressure within a pilot assembly to manipulate the piston.The pilot assembly comprises pilot means within the housing, having valve seat means thereon. Normally free traveling spherical members define valve head means selectively sealingly engagable on the pilot means to open and close the pilot means. A pilot spool permits selective movement of the spherical members to the immediate vicinity of the valve seat means of the pilot means.

Abstract: A valve is disclosed which controls flow of fluid through its body from inlet to outlet, and which has a co-operating valve seat and valve closure member. The closure member is actuated by an operating element which comprises an integral stem and diaphragm, the stem projecting from both faces of the diaphragm. One stem part is connected to the closure member and the other part is free and acts as the actuating member. The diaphragm is secured in and seals the aperture through which the stem projects from the valve body. Heat-sealing of the periphery of the diaphragm to the bounding wall of the aperture is disclosed, and the stem can be stiffened by a metal rod embedded therein. The diaphragm is distorted and acts as a pivot for the stem when the free part of the stem is displaced. The valve is disclosed as forming part of an air-gun and as part of a bath shower unit.

Abstract: A valve comprising a body having a straight-through flow passage, a valve head moveable at an acute angle with the downstream end of the passage into and out of the passage, and a valve seat extending about the passage for cooperation with the valve head to adjust the valve over a range from the wide-open to the closed condition, the valve seat approaching the axis of the passage no more closely than does the wall of the narrowest portion of the passage upstream or downstream of the seat, whereby in the wide-open condition, the valve head is removed from the passage, the axis of the passage remains a straight line, and the cross-sectional area of the passage at the position of the seat is no less than it is at the narrowest portion of the passage upstream or downstream of the seat.

Abstract: A novel cylindrical valve plug for the ported bore in valve, particularly a class of hot and cold water mixing valves, is disclosed. The plug, in an illustrative embodiment, comprises an inner cylindrical core, a non-metallic, yieldable elastic sleeve compressed about the sleeve, and placed under radial compression inside the valve bore, so as to bear and exert pressure radially outward on the inner wall of the valve bore.A multiplicity of small serrations on the surface of the core penetrate partially (but with non-cutting indentation rather than puncture) into the sleeve when the sleeve is compressed, leaving air pockets in the valleys of the serrations. When, owing to any cause, such as temperature rise, the compression of the sleeve rises, it expands elastically into the "breathing space" afforded by these pockets, instead of increasing the radial pressure between the valve plug and the valve bore, such as would increase the resistance to turning or to axial travel of the valve plug.
