A biased slidable member is positioned in the bore and provides for fluid flow between the fluid inlet and outlet when the valve is in a first position. High flow and stop flow positions are also provided upon compression of the trigger. The valve can be employed in conjunction with a combined spray and aerator head, as well as a hose take-up assembly.

Abstract: A paint dosage device is particularly adapted to be mounted in close proximity to a spray gun (P) in a program controlled spray painting installation for dosed paint supply to the spray gun. The device includes at least two dosage cylinders (SA,SB), each having a regulating piston (PA,PB) connected to a piston departure position and displacement velocity regulator (RA,MA:RB,MB) for setting the paint filling amount of the associated cylinder by controlled adjustment of the departure position of the regulating piston in the cylinder, and for setting the dosage rate of the cylinder when supplying paint to the spray gun, by program controlling the displacement velocity of the regulating piston in the cylinder. A valve assembly (V1,V2,V3,V4) is arranged for connecting the cylinders (SA,SB) alternately to the spray gun (P) and putting the cylinder disconnected from the gun in connection with means for cleansing and paint filling apparatus.

Abstract: An externally adjustable restriction control assembly for a poppet valve. The restriction control assembly is actuated through rotation of the valve stem. Upon rotation of the valve stem, a restriction control disc, threadably mounted to the valve stem guide, is moved toward or away from a seat provided within the housing. Movement of the restriction control disc thereby adjusts the effective cross-sectional flow area through the valve.

Abstract: A tilt valve cartridge for a pneumatic mechanism has a cylindrical housing having two open ends, an annular valve seat secured in one open end, a valve member in tiltable contact with the annular seat and having a valve stem which extends through the valve seat and protrudes from the end of the cylinder, a spring to hold the valve member in a normally closed relationship with the valve seat, a sealing element secured to the cylindrical housing on its exterior surface so as to seal the interface between the cartridge and the mechanism, and retention feature to capture the valve member and valve biasing spring within the cylindrical cartridge. The modular cartridge feature simplifies installation and replacement of the valve in the inlet air passage of the pneumatic mechanism.

Abstract: A valve assembly for use with a fluid-driven tool having an elongated conduit with a bore communicating with the source of fluid, and an elongated valve member received in the bore. The valve assembly has a ball received in a chamber defining a valve seat, with the chamber communicating with the source in order to drive the ball against the seat. The valve assembly has a valve pin extending through the conduit in order to actuate and move the ball away from the valve seat to permit passage of the fluid through the valve member past the seat, and a paddle for actuating the valve pin in order to open the valve.

Abstract: Disclosed herein is a flow change-over valve for the blowing of fluids into a molten metal vessel, which includes a housing provided with at least three inlet ports for different fluids and an outlet port, a valve body with a main passage communicating selectively between one of the inlet ports and the outlet port and rotatably supported in the housing to perform the changing-over of inlet passages. Among these inlet ports, an inlet port for purging fluid is opened in the housing, and a shroud-like gap surrounding the valve body is formed between the inner periphery of the housing and the outer periphery of the valve body in such a manner that it communicates with the inlet port for the purging fluid disposed in the housing and is always to be communicated with an opening of an inlet port of the main passage during the changing-over through the rotation of the valve body.

Abstract: A valve operating mechanism for an internal combustion engine for an automobile in which friction is decreased without an increase in the mass to be moved by the valve closing spring. The valve operating mechanism has a roller arranged on an actuation spindle. The roller cooperates with a bearing surface on a component of the mechanism that is connected to the valve, at least during valve opening, so that deviations of the valve lift curve from the desired valve lift curve are eliminated. Connection between the actuation spindle, through the roller, and the valve is maintained only during the valve-open cycle.

Abstract: A tractor hydraulic power lift mechanism has a known manually adjustable flow control valve for regulating the rate of lowering an implement. However, when the valve is so adjusted that a heavy ground-working implement is lowered to ground level at a rate slow enough not to cause damage, the implement is then very slow to penetrate the ground to the desired working depth. A manually operable overriding mechanism preferably actuated by the main hand lever of the power lift mechanism is therefore provided to enable the valve to be moved temporarily into its fully open position and allowed to return to its adjusted position. The overriding mechanism is operated as the implement reaches ground level and released when it reaches its working depth.

Abstract: A fluid control valve assembly comprises a pair of identical valves mounted on a manifold with connections to the controlled actuator and to the high and low pressure sides of a fluid circuit incorporating a pump or other source of high-pressure fluid. Each valve includes a reciprocating tappet directly connected to a conical valve head and spring biased into a closed position of the valve, with a portion of the tappet protruding from the valve body. Superimposed on the two protruding tappets is a rocking beam which may be pivoted into contact with either tappet by means of a handwheel engaged in a bracket. A threaded shaft affixed to the handwheel passes through a nut pivotally secured to the rocking beam, so that rotation of the handwheel in either sense will result in the depression of one of the two valve tappets and the opening of the valve associated therewith.

Abstract: An automatic dispensing nozzle of the type for dispensing liquid such as gasoline, or the like, into a container and for automatically shutting off when the container is full. The assembly includes a housing having a fluid inlet and an outlet with the fluid passage extending therebetween and a valve disposed in the passage with a valve actuating stem extending exteriorly of the housing. A handle guard including a downwardly extending guide portion and a forwardly extending guard stem. A handle is pivotally supported at a front end adjacent the connection of the handle guard to the housing and extends to a rear end disposed adjacent the guide portion of the handle guard and engages the valve actuating stem for moving the valve actuating stem upon pivotal movement of the handle. The guide portion of the handle guard includes a forwardly extending rib and the rear end of the handle means is bifurcated to define flanges disposed on either side of the rib.
