ORO valve

ORO the pressure control valve outlet pressureregulating valve, which responds to changes in pressure in the receiver. Valve designation stands for offers on increase of pressure on the outlet (see Fig. 11 to 33). The inlet and outlet pressure on the underside of the seat drive towards the opening. Since the area of a small port, depending on the diaphragm region inlet pressure has little effect on the operation of the valve. The socket or the receiver pressure is the pressure in the control system. In force at the top of the diaphragm, which is against the pressure control of the air battery. These two forces operating forces ORO.

When the external temperature changes condensing pressure changes. This causes the pressure in the receiver fluctuate accordingly. As a receiver pressure decreases, ORO regulates the flow of liquid from the condenser. As a receiver, the increase in pressure, the valve modulates the opening direction to maintain a nearly constant pressure
in the receiver. As the temperature of the element affects the pressure valve, pressure control may change slightly when the ambient temperature changes. However, fixtures and elements of the temperature remains practically unchanged.
