Solenoid valve

A two-port solenoid valve of the pilot-assisted type that is designed to function even when there is no pressure difference between the primary and secondary control passages. A pilot valve actuated by the armature of a solenoid opens and closes a pilot discharge passage, with the armature being also adapted to open the main valve that is connected thereto by means of a lifting spring. The pilot discharge passage immovably provided in the valve housing is intended for suppressing the vibration of the main valve in closing. The pilot valve thart comes in and out of contact with the pilot valve seat at one end of the pilot discharge passage is spring-thrusted in the closing direction and attached to the armature. An inwardly projecting hitching rim is provided at the bottom of the armature that is adapted to stop the pilot valve toward the end of the attraction stroke in which the armature is pulled toward the stationary core, thereby ensuring that the pilot valve is released while a large ...

... 1322107 Valves FIAT SpA 21 July 1971 [26 Feb 1971] 34235/71 Heading F2V In a normally-open valve a plunger 144 of a solenoid 146 is normally biased upwards by a tension spring 145 but on energization of the solenoid moves downwards to abut a diaphragm closure member 126 and move it against a seat 120 between an inlet 112 and an outlet 114. Simultaneously, a spring-loaded disc 154 closes a bore 142 through the diaphragm which also has a restriction 140 therethrough. When the plunger is in the normal upper position, flow through the valve can take place in either direction since P.T.F.E. ball 15 prevents flow from the outlet to the inlet from causing a pressure build-up above the diaphragm which would close the valve. The valve may be normally-closed.

In a two-stage control valve a double-acting pilot valve member 206, is displaceable in response to an electric signal to vary the flow of fluid through two pilot orifices 120, 122 carried on the main valve spool 88 to create a pressure differential which acts on the end of the spool to move it.

[Also in Group XXIX] In an electromagnetically-actuated fluid control valve for a vehicle braking system, air from a container, not shown, which enters a space A, Fig. 1, between two double-conical valve closures 20 and 26 lifts the small closure 20 so that its upper cone shuts a discharge port 17 in a pilot piston 15 connected to a spring-loaded solenoid armature 9 whereupon air from the space A flows past the lower cone of the closure 20 through a channel C to lift a control piston 24. Air pressure below the pilot piston 15 opposes the weight of the latter as well as that of the moving parts of the solenoid, the force of the solenoid spring and the thrust of the energized solenoid.

Self draining valve

A self-draining, valve for fluid flow control. Upon removal of fluid supply pressure from the valve, the valve automatically reverts to a partially open state allowing fluid in the valve to drain. The disclosed valve is particularly useful in applications where draining of fluids with bio-matter or other contaminants is desired after removal of supply pressure in order to reduce contamination buildup and/or permit thorough cleaning.

Electromagnetically controlled valve for high pressure fluids.

Valve for high pressure fluids of the type of those in which the flap is pushed against its seat by the interposition of a spring, characterised in that the main flap 7 has a central orifice 14, which is shut-off by a flap 15 for discharging the pressurised fluid contained in the valve, of which the axial displacement is controlled by an electromagnet 19 having a solenoid plunger. The flap 7 forms a piston making a chamber containing the high pressure fluid in the body of the valve, which fluid penetrates into said chamber via calibrated orifices and via the interstices resulting from the play between the movable parts, the total cross section allowing the passage of the fluid being much less than the cross section of the seat of the auxiliary flap; the core 18 of the electromagnet is housed in the aforementioned pressurised chamber.

Axial solenoid valve for automating opening and closing of hydrants

The valve is fitted to water hydrants and has the fluid inlet and fluid outlet on different axes. The fluid inlet is through a hole (4) in the bottom of the valve and the fluid outflow is radial, through holes (6) in the periphery of the valve. A membrane (12) positioned across the inlet hole can block the fluid inlet (4). The membrane divides the interior of the solenoid valve into two chambers (11) and (5). When the solenoid (9) is in the higher position the upper chamber is emptied and the membrane rises. In the lower position water cannot pass to the upper chamber and the membrane blocks the water inlet hole (4).
