    摘要: A line pressure responsive flow control valve (46) is in series with a solenoid (34) operated off-on valve (26). These two valves (46, 26) are in a common housing having an inlet port (94) and an outlet port (96). A branch (24) of a bypass line (24, 24') extends from a fuel delivery line (10) to a fuel tank (16). A spring (76) biases a closure wall (70) of a piston (66) into contact with a valve seat (88) surrounding a valve orifice (90). Fuel pressure at the inlet (24) acts on the closure wall (70). When this pressure exceeds a predetermined minimum, the piston (66) is moved so as to open the valve orifice (90), allowing fuel to flow from the bypass line (24) to the off-on valve (26). The line pressure responsive flow control valve (46) functions to control flow through the bypass line (24, 24') at times when the off-on valve (26) is open.

    摘要: A two-way fluid control valve for use in temperature controlled HVAC systems. The control valve includes an engine coolant inlet and an engine coolant outlet. A diaphragm is located between the inlet and outlet and is movable between a closed position in which it prevents coolant flow through the control valve and an open position in which it allows coolant to flow through the control valve. A pressure chamber above the diaphragm is in fluid connection with the common port of a three-way control solenoid. The inlet is in fluid connection with the normally closed port of the solenoid and the outlet is in fluid connection with the normally open port of the solenoid. In an unenergized position, the pressure chamber is maintained at a lower pressure than the coolant pressure in the outlet, allowing the diaphragm to be forced open by the engine coolant, thus allowing engine coolant to flow through the valve. In an energized mode, the pressure chamber is maintained at the same pressure as the inlet, thus allowing a spring to bias the diaphragm into a closed position in which engine coolant is prevented from flowing through the valve.

    摘要: A venting valve (2) for a liquid tank, such as a vehicle fuel tank, has a float (64) confined in a cage (10). A valve element (86) is mounted on a mounting post (76, 78) carried by the top surface (72) of the float (64). The element (86) is pivotable about a horizontal axis (X). A rising liquid level in the cage (10) causes the float (64) to move upwardly and seat the valve element (86) against a valve seat (42). When the liquid level falls and the float (64) descends, the valve element (86) pivots on the mounting post (76, 78) and thereby acts as a lever to increase the effective weight of the float (64). This enables the lightweight float (64) to overcome vapor pressure in the tank and unseat the valve element (86). The valve of the invention may be incorporated into a cap (102) for closing a vehicle fuel tank filling and venting tube.

    摘要: Separate valve bodies (16, 18) are connected by a sleeve (24). The joint (26) between the first body (16) and the sleeve (24) is detachable by bending forces and resistent to tension forces. The joint (32) between the second body (18) and the sleeve (24) is detachable by tension forces and resistant to bending forces. Each joint (26, 32) includes an annular groove (28, 34) on the valve body (16, 18) and portions (30, 36) of the sleeve (24) extending radially into the groove (28, 34). Each valve body (16, 18) has a valve element (44) that moves axially inwardly to close the flow passage (42) when one of the joints (26, 32) is detached. The valve element (44) is normally retained in an open position by a ball detent (84). A projection (82) carried by the confronting valve body (16, 18) holds the ball (84) in a groove (62) on the element's shaft portion (56). In a vehicle (2) having two fuel tanks (4) connected by a crossover line (10), a valve (14) is positioned at each end of the line (10) between the line (10) and the associated tank (4).

    摘要: A gas vent orifice (78, 148) is located within a gas vent passageway. A closure ball (80, 154) is located upstream of the orifice (78, 148). A piston (66, 166) is located downstream of the orifice (78, 148). The piston (66, 166) includes a projection (76, 170) which projects into the orifice (78, 148), for dislodging the closure ball (80, 154) from its seated position. A mass in the form of a spherical ball (74, 160) functions to move the piston (66, 166) to dislodge the closure ball (80, 154). The mass (80, 154) rests on a conical ramp (56, 126) and the slope of the ramp serves to direct the mass (80, 154) against the piston (66, 166). A steep sloped ramp (126) may be used in combination with a piston (166) having a cylindrical center portion (168). Or, a shallow ramp (56) may be used in combination with a piston (66) having a flat upper surface and radial legs (68, 70) which fit within radial slots (58) in the ramp (56).

    摘要: A normally closed pneumatic valve and regulator assembly having regulator and vent valve spools is actuated by an operator pushbutton to automatically regulate pressure of a fluid provided from a pressure source. The valve assembly automatically vents when the pushbutton is released. A bias spring is operatively positioned between the pushbutton and one of the valve spools. The spring is preloaded by a pair of interlinked hook members which limits the travel of the pushbutton with respect to the valve spool and which maintains the spring in a preloaded condition so as to set a minimum value of regulated pressure. Fluid pressure from the pressure source urges the regulator valve spool into a normally closed position and the vent valve spool into an opened position. Pushing the pushbutton opens the regulator valve and closes the vent valve. The spring acts in opposition to fluid pressure on the combined valve spools to provide a regulated, reduced pressure for fluid exiting the valve. When the pushbutton is released, fluid pressure urges the valve spool into the normally closed position uncovering a vent hole to release pressurized fluid from the valve outlet.

    摘要: Venting gas flow from a fuel tank or the like enters through tangential inlets into a spin chamber, influencing a closure ball in said chamber to spin or orbit around an upper conical wall portion of the spin chamber. The spinning action keeps the closure ball from seating in an outlet opening formed at the upper end of the spin chamber. The closure ball does seat in response to liquid rising in the spin chamber or tilting of the spin chamber beyond a predetermined angle of tilt. A vibrating mass positioned on the outlet side of the outlet opening includes a central striker portion which contacts the closure ball whenever it tends to seat in response to shock forces or some condition other than the presence of liquid activated buoyancy forces or tilt activated gravity forces.
