Abstract: A solenoid-operated pneumatic valve in which the air vent tube has a nut threaded onto the one end thereof. A first sealing portion of the nut engages the solenoid valve body and a second sealing portion engages the air vent tube to prevent the entry of dirt and moisture into the area of the magnetic coil. The nut is further formed with an undercut portion over which a protective cover is snapped into position. The inside of the cover is provided with a conical portion to deflect the exhaust air for sound damping.

Abstract: A three-way valve device or the like having valving that is operably disposed within a bushing contained in the housing of the valve device, and a permanent magnet that is disposed in surrounding relationship with the bushing so as to be operable along the axial dimension thereof from an inactive position that is magnetically remote from a movable member of the valving to an active position that is in magnetic proximity with the movable valve member, to thereby shift the valve member and accordingly control fluid pressure communication between the valve porting with snap action. In one embodiment of the invention, the permanent magnet is operated by a push-button against the action of a spring, and in a second embodiment, the permanent magnet is encapsulated within a fluid-pressure-operated member subject to fluid pressure on its opposite sides.

Abstract: A valve battery device including mounting plates on which valves may be mounted, and of which a preselected number, each having passageways therein, may be assembled in serial relation to form a valve battery of any desired number. Each mounting plate is provided with one hooked projection and one recess for accommodating the hooked projection of an adjacent mounting plate, and all mounting plates are identical in structure and so constructed that they may be turned end-for-end and top-for-bottom so they may universally assemble. Identically structured terminating plates are provided at each end of the valve battery.
