ABSTRACT:
A body, having ported plates astride a third plate having a void formed therein, confines a ball-type valving element therein, in a chamber defined by the void. Ports in the ported plates open onto the chamber, and the ported plate on the outlet side of the valve further has a metering orifice formed therein which opens onto the chamber. Fluid flow proceeds from the plate on the inlet side, through the chamber, and out through the metering orifice. The configuration, for a given fluid having a prescribed forward pressure differential, controls the flow rate. Additionally, the pressure differential securely holds the valving element on its valve-open seat, and substantially diminishes false closing and ball chatter.
