Abstract
An improved valve for a pulsating submergible pool cleaner having a valve body (20) with an integral relief valve (32). The valve is dual acting and utilizes a pair of opposed laminated valve plates (50) with an outward bend (52) on one end and a right angle bend (54) on the other. When negative pressure is applied to the opposed plates, each plate draws together over a fulcrum (26) until the right angle bend touches a restrictive boundary in a cage (28) integral with the body creating the first step in the dual action. When negative pressure continues, the valve plates arcuately bow until the outward bends contiguously abut, closing the valve to fluid flow and creating the final step in the dual action. A garter spring (60) pulls the valves plates into their original parallel position when pressure is relieved.
Claims19
An improved reed valve for a pulsating submersible pool cleaner comprising;
- a valve body forming an enclosure having a fulcrum, a plurality of grooves and a restricting boundary for retaining and confining valve movements,
- a pair of opposed dual acting valve plates juxtaposed within the valve body, each having a first end and a second end, with each first end including an angular outward bend facing away from each opposed plate such that when both plates are simultaneously inwardly deformed by negative fluid pressure applied to the pool cleaner, each outward bend ultimately engages a mating plate for valve closure, and
- a continuously wound extension garter spring disposed within the grooves in the valve body surrounding the opposed pair of valve plates adjacent to their second end, permitting the first end of each valve plate to contract inwardly against the fulcrum of the body until both the second end of each valve plate and the spring simultaneously engage the restrictive boundary of the body, producing an initial valve action and under increased negative fluid pressure, the valve plates deform until each outward bend makes intimate contact with each other, thereby closing the valve and impeding fluid flow through the valve completing a final and dual action.
An improved reed valve for a pulsating submersible pool cleaner comprising;
- a thermoplastic valve body forming an enclosure having a fulcrum, a plurality of grooves and a restricting boundary for retaining an confining valve movements,
- a pair of opposed dual acting laminated valve plates juxtaposed within the valve body, each having a first end and a second end with each first end including an angular outward bend from 25 to 35 degrees facing away from each opposed plate such that when both plates are simultaneously inwardly deformed by negative fluid pressure applied to the pool cleaner, each outward bend ultimately engages a mating plate for valve closure, and
- a continuously wound extension garter spring disposed within a single pair of grooves in the valve body surrounding the opposed pair of valve plates adjacent to their second end permitting the first end of each valve plate to contract inwardly against the fulcrum of the body until both the second end of each valve plate and the spring simultaneously engage the restrictive boundary of the body, producing an initial valve action and under increased negative fluid pressure the valve plates deform until each outward bend make intimate contact with each other, thereby closing the valve and impeding fluid flow through the valve completing a final and dual action.
