In an apparatus using fluid, the flow of the fluid is normally controlled by using various kinds of valves. For intercepting lines of fluid, a solenoid valve is often used as a valve for controlling opening and closing of the fluid lines, while as a valve for intercepting a backflow of fluid, a chec

An annular valve member having an annular, peripheral recess therein defining an axially facing shoulder at the periphery of the valve member and a reduced diameter axially projecting boss at the center of the valve member.

A fluid flow-controlling valve comprising valve body, a central cylindrical bore in said body with one end thereof being the normal valve inlet and the other end the normal valve outlet, a valve seat extending around said bore, a hollow cylindrical relief valve element coaxial with and arranged for

A drain valve to be used with numerous drain applications, such as draining fluid from an engine, includes in an exemplary embodiment a valve body, a first and second o-ring and a valve sleeve.

The valve of the present invention is adapted for use with a pressurized aerosol dispensing container and comprises an axially movable, tubular valve body; a diaphragm integral with the valve body and urging it upwardly toward closure;

In consequence the invention is based on the object of avoiding the above disadvantages and providing a control valve which has a high closing force with a small actuating force, as well as facilitating a simple and compact construction.

The present invention relates to a valve particularly suitable for use in dispensing hot glue although it may be used for dispensing any fluid. The valve has a hollow discharge arm which turns the valve stem against a spring actuated piston.

It is common practice to employ disc or poppet valves for the above-described application, and several valve discs may be mounted on a common stem. The known valves quickly open the aperture in a valve seat when moving away from the same, and suddenly block liquid flow as they engage the valve seat.
