ELECTRICALLY OPERATED VALVE AND PROCESS FOR THE ASSEMBLY THEREOF

Solenoid valve and air pressure massage device

A solenoid valve with a small-size light-weight check valve. In the solenoid valve, a voltage is applied to a solenoid (14) to move a plunger (16) toward an end wall (22) of a housing of the solenoid valve. This presses an annular valve seat engagement section (64) of a valve body (48), which is attached to the plunger, against a valve seat around a fluid exit (26) formed in the end wall (22). As a result, the fluid exit (26) is closed with the annular valve seat engagement section deformed, and at the same time, a valve pressing member (46) attached to the plunger is separated from a valve body (52) provided at a fluid entrance (24) in an end wall (20) in the housing. This causes the valve body (52), formed at the fluid opening (24) of the housing, to function as a check valve to allow inflow of pressurized air from a pump. When the voltage is not applied to the solenoid (14), the plunger (16) is urged toward the fluid entrance by a compression spring (60). This makes the valve pressing ...

A control valve for controlling the flow of hydraulic fluid

A control valve of the three port, two position variety consists of a housing 10, within which is fitted a sliding sleeve 11. Three fluid conduits or ports 12, 14 and 16 are located within the housing, the first being an inlet, the second being to a reservoir, while the third conduit 16 is connected to an actuator. The sleeve 11 mounted within the valve chamber moves under the influence of a magnetic flux generated by an electrical coil 19, and can be in contact with either of two spaced apart valve seats 23 and 22, allowing the fluid to flow either to the reservoir from the actuator, or from the inlet to the actuator, depending on the position of the sleeve. In a different embodiment, the inlet and reservoir connections can be reversed.

Pilot actuated spool valve

A housing has a cage with supply fluid ports, vent ports and an outlet port. A pilot actuated hollow spool valve element is telescopically movable in the cage and engages poppet seats at opposite ends of the cage. Elongated supply and vent slots directed transversely to the axis of the cage and valve element provide maximum flow passages. The ends of the spool are in contact with the cage at all times and the axial extent of the contact between the spool and the cage is greater than fifty percent. The spool engages the interior of the cage at the fluid ports and vent ports for reducing flow restrictions. A recess coaxially positioned at each end of the cage receives one of the valve seats. The housing abuts the cage for properly loading the valve seats. A dash pot cushions the valve element. A pilot control stem is connected to the valve element exteriorly of the valve element. A seal carrier provides a seal between mating surfaces of an underwater control pod.

The invention relates to the food industry, in particular to shop equipment, and can be used for dispensing beer and other foaming and/or effervescent beverages from an isobaric container into plastic bottles or glasses at stalls, restaurants and bars. Said invention makes it possible to simplify the maintenance of the entire beer dispensing device by excluding the necessity of sanitizing a part of a pouring tube after each filling of the container as well as the maintenance of valves owing to the lack of necessity for repeatedly washing the units and parts of said mechanisms after dispensing beer or another beverage. The technical result is achieved by two variants of design of a three-way valve accommodated in the device for manually dispensing foaming and/or effervescent beverages into an open receptacle.

FAST SWITCHING 3/2 DIRECT OPERATED HYDRAULIC DIRECTIONAL CONTROL VALVE

The new valve incorporates a poppet or spool that covers one of two ports at one position, and then switches to cover another port at a second position. In each of the two positions, it separates the covered port from a third port, and connects this third port with the uncovered port, and it reverses the connections at the second position. To ensure high speed of response, the poppet or spool has lowest possible mass and consequently inertia, it switches between the two positions in short stroke by the action of an actuator, and returns by the action of the liquid (or the gas in other applications) high pressure that could provide high displacing force, or by a spring, or by both. The high pressure is applied to two nearly equal areas at the two sides of the poppet or spool, and thus two merits are gained: the actuator force should overcome the force of the pressure applied only on a small differential area instead of a large area, and the poppet or spool thicknesses can be reduced to reduce the mass and consequently the inertia. As special case, two ports of the valve can be used instead of three, and the third one can be connected to a high pressure source to be used as pilot pressure for fast returning of the poppet. It could continuously connect or separate between any two ports at both working positions with any pattern of connections.
