Abstract
A relief valve for use with automatic suction operated swimming pool cleaners which has a tubular body and a bypass passage into the body inclined at an acute angle to the inlet and controlled by a closure pivotally supported about an end upstream of the normal flow direction through the valve and with the closure biased, preferably by at least one tension spring, to the closed position.
Claims11
A relief valve comprising a tubular body having an inlet and an outlet, a by-pass trough a connection passage inclined at an acute angle of between 5.degree. and 50.degree. to the body with respect to the inlet, the passage being of U-shape in cross-section, a closure for the by-pass pivotally supported therein between the ends of the arms of the U-shape to open in an upstream direction of normal flow through the body and biasing means to hold the closure in the closed position in the form of at least one tension spring anchored to the body at one end and to an extension to the opposite side of the pivot support from the by-pass closure at the other.
A relief valve comprising a tubular body having an inlet and an outlet, a by-pass through a connection passage inclined at an acute angle of between 5.degree. and 50.degree. to the body with respect to the inlet, said connection passage being of U-shape in cross-section, a closure for the by-pass pivotally supported therein between the ends of the arms of the U-shape to open in an upstream direction of normal flow through the body and biasing means to hold the closure in the closed position.
