Abstract: A pressure regulation servo-valve comprising a body having a utilization port, a feed port, and a return port, a spool mounted as a sliding fit in the body, the spool co-operating with the body to define a pilot chamber connected to the utilization port. The spool and the body together further define a priming chamber connected to the feed port via a second constriction and connected to the nozzle via a third constriction, and in which there exists a priming pressure acting on the spool in the first direction.

Abstract: A control valve includes a single diaphragm as a common wall between an input signal chamber having an input port and an output chamber having a central supply port and an exhaust orifice. The orifice has a seating face parallel to and spaced from the diaphragm. A spring-loaded ball valve unit in the supply passage is aligned with an operator moving with the diaphragm. An increasing input signal first moves the diaphragm to close the exhaust orifice and thereafter moves the operator to open the supply valve. Pressure builds in the output chamber, tending to return the diaphragm and close the supply valve until the output and pilot pressure are balanced. The supply valve then closes. As the exhaust is sealed off, this effectively seals the output chamber. If the signal decreases, the diaphragm uncovers the exhaust orifice until a new balanced state is created. In high flow capacity systems a multiplicity of exhaust orifices are employed to match exhaust and supply flow capacity while maintaining minimal leakage.

Abstract: A control device having a pressure sensing element coupled to a balance plate. The balance plate, in turn, is coupled to a microswitch by an actuating rod. Variations in pressure displace the sensing element which, in turn, pivotally displaces the balance plate sequentially about first and second axes. A pair of springs are coupled to the balance plate by bosses which extend different distances from the balance plate. The bosses facilitate use of identical springs and adjusting members in a control device where the differential between control points is fully adjustable. The control device has a housing including upper and lower sections, the upper section having a microswitch associated therewith, the lower section having the balance plate and associated elements disposed therein. A recessed space at the exterior of the housing is defined by the upper and lower housing sections. The adjusting members for the springs extend into the recessed space so as to be readily accessible from the exterior of the housing. The control device includes a detachable pressure transducer which facilitates conversion of the control device from one application to another.

Abstract: A weighing valve mounted on a vehicle to produce a fluid having a pressure proportional to the load of the vehicle is activated by a force translating device which produces a proportionate force to the valve to thereby generate fluid flow changes of pressure signalling the loading on the vehicle. The force translating device has a differential piston with a plunger of smaller diameter for actuating the valve communicating with a plunger of larger diameter responsive to the load. The plunger and piston are interconnected through a deformable, incompressible medium such as silicone rubber into which both the end and sides of the smaller diameter plunger are extended thereby dampening vibrations.
