TH136460A - Vent vacuum relief valve for safety vacuum release system - Google Patents

Abstract

DC60 (10/06/56) Various features of this invention provide a vacuum relief pump and valve system. Discharge type for use in hydraulic systems incorporating a safety vacuum release pump. To circulate water in swimming pools and / or spas The hydraulic system consists of a non-return valve. Or several pieces on the vent side of the safety vacuum release system pump Vacuum relief valve Vent type can eject the vacuum at the vent side of the pump. During the presence of vacuum on the suction side of the pump, a safety vacuum release system
