ABSTRACT:
There is here provided an electrically operated valve primarily for the control of a pressurized gas, such as air, and particularly adapted for manufacture in very small units. The electrical components and parts reactive thereto are so constructed and arranged that they can be made in very small sizes without excessive expense but with the resulting product being nevertheless reliable, sturdy and resistive to damage. The structural components of the operator means are held together by resilient means and the solenoid coils encircle the operating plunger and said plunger acts in one embodiment through a spring against an actuator, all such constructions being effective to eliminate the effect of construction variations. Further, there is provided a unique porting arrangement by which relatively large conduits may be attached to the valve unit, and by which, with other constructional characteristics, render the valve capable with only simple modifications to function in a variety of different modes. Lastly, the valve operator is uniquely constructed to reduce the residual magnetism which reduces the size of the return spring required and hence reduces the size of the operating solenoid. All of this reduces the size of the electrical components which still further reduces the size of the valve, renders the valve more efficient and advantageously reduces the size, complexity and expense of external control and supply apparatus.
