Abstract
Abstract A positive sealing, self-adjusting valve seat is provided for a ported valve having an especially configured valve chamber therein. The chamber includes a shouldered portion extending therein to divide same into a first chamber portion communicating with a first port and a second chamber portion communicating with a second port. The valve seat is defined by an annular resilient disc member abutting the shoulder and housed in an especially configured retainer seat. The retainer seat is constantly spring biased to maintain the resilient disc in sealing engagement with the shoulder and thus prevents leakage between the first and second chamber portions. Valving is accomplished by a ball-type valve normally spring biased into sealing engagement with the opening in the valve seat and unseated therefrom by actuating means operated in accordance with a condition sensing device.
