摘要： A spring biased normally open solenoid actuated valve includes a valve body having a valve seat defining a valve port, located between an inlet port and an outlet port, that is controlled by a spool. When the solenoid is de-energized, the valve spool is biased open by a compression spring. The valve spool may include a double seal assembly expanding the range of operating pressures for a given spring force. The double seal assembly includes a rod having first and second ends with the first end secured to a stem of the spool. A retainer including a first sealing surface is secured to the second end of the rod. A sealing member, longitudinally moveable along the rod, is concentrically located on the rod adjacent the retainer and includes an inner valve seat and a second sealing surface such that the first sealing surface contacts the inner valve seat and the second sealing surface contacts the valve port when the solenoid is energized thus closing the valve. When the solenoid is deactivated intentionally or due to an electrical failure the valve fails to an open position. The valve spool may include a sleeve secured about the rod, positioned adjacent the sealing member so that when the valve stem is moved from a sealing position to an open position, the sleeve contacts the sealing member after movement of the stem has commenced.

The flow control device including a high pressure region and a low pressure region downstream of the high pressure region with the high pressure region of the flow control device including a flow control orifice having an inside diameter less than a diameter of the fluid outlet and the low pressure region of the flow control device intersects the high pressure region of the flow control device. Additionally, the low pressure region has a first dimension less than the inside diameter of the orifice and a second dimension greater than the inside diameter of the orifice, with the second dimension being transverse to the first dimension. The body of the aid flow control device includes a substantially cylindrical portion and a substantially conical portion with the conical portion being positioned downstream of the cylindrical portion which includes the high pressure region while the conical portion includes said low pressure region.

摘要： A control valve assembly for selectively controlling a flow of fluid through a fluid flow system is disclosed including a valve housing having a fluid inlet and a fluid outlet, a valve seat positioned about the fluid outlet and a sealing diaphragm for cooperating with the valve seat for selectively sealing off fluid communication between the fluid inlet and the fluid outlet. The diaphragm fluidically separates a pressure chamber from a control chamber within the housing. A central control orifice is formed in the diaphragm for fluidically communicating between the control chamber and the fluid outlet, an armature is reciprocally received in the housing for selectively sealing off fluid communication between the control chamber and the fluid outlet with at least two bleed orifices formed on the diaphragm which fluidically communicate between the pressure chamber and the control chamber. Extending into each of the bleed orifices is a metering element for controlling a flow of fluid between the pressure chamber and the control chamber for softening the return of the diaphragm to the closed position thereby eliminating compressive shock to the assembly. Preferably, the bleed orifices are diametrically opposed to one another and formed in a thinned region of the diaphragm which bridges a fixed outer periphery and a central region of the diaphragm.
