Title: Instant-on valve construction for high pressure gas
Inventor: KHADIM NEIL
IPC: F17C13/04
Filed: 1996-07-15
Abstract: A valve construction  for high pressure gases, allowing rapid opening and closing, includes a main body with inlet and outlet passages, and a guide sleevehaving a primary and a secondary piston slidably mounted within the sleeve, the primary piston being adjacent a closure at one end of the sleeve, and the secondary piston being at the end of the primary piston which is remote from the closure.  The secondary piston supports a seal for closing the gas outlet passage when the secondary piston is remote from the closure.  The secondary piston has an axial passage with an elongate member movable therein, the elongate member being fixed to the primary piston.  A valve means is provided between the axial passage and  the  elongate member, the valve means being open when the bleed orifice is closed.  A peripheral seal between the secondary piston and the sleeve acts to restrain the axial movement of gas.  An access passage connects the periphery  of the secondary piston with a location on the axial passage, while a passageway  in the secondary piston connects the region between the first and second pistons with the bleed orifice chamber.  An electrical coil acts to generate a magnetic field.  The valve construction  thus defined is in equilibrium  when the coil is de-energized, the seal means closing the gas outlet passage, the closure portion closing the bleed orifice, and the primary piston being furthest remote from the closure.  When the coil is energized,  the  primary  piston moves toward the closure until the valve means closes, lifting the closure portion off the bleed orifice and permitting gas  to  escape from  around the  primary  piston, through said passageway, and out the bleed orifice, thus resulting in an increase in the pressure differential across the peripheral seal.

Patent CA-2193168-A1 (CA)
Inventor: WETZEL UWE
IPC: B30B15/00
Filed: 1996-12-17
Abstract: A control device contains two electromagnets (61, 62) in a respective current supply circuit (41, 44; 42, 44) which includes a biassed switch (20, 21) having first and second output terminals (2, 4), wherein the switches are biassed towards the first output terminal (2). When the magnets are moved to an active state against a biassing force, the switch in one circuit switches from its first (2) to its second terminal (4) to which the magnet is connected. The first and second terminals (2, 4) of the two switches (20, 21) are connected crosswise, so that a control signal (S1, S2) to the first circuit will initially energize the magnet of the second circuit, and vice versa, wherein the magnet remains in an active state if switching of the switches takes place within the time period taken for one of the magnets to leave its activated state after deactivation, i.e. when the two control signals (S1, S2) are both applied within this time period. The control device may be used, for instance, for the two-hand control of pneumatic clutches and brakes in an eccentric press.
