Abstract

A combination check-flow control and selector valve that distributes fluid from a single inlet sequentially out through a plurality of outlets. The valve includes a housing with a selector chamber having a centrally located inlet and a plurality of outlets, a replaceable sequencing cam adjacent the top of the housing, a check-flow control valve means movable into and out of an inlet, and a selector valve including a sequencing sealing means rotatable and movable toward and away from the outlets. The selector valve is connected to the replaceable cam to direct the step-by-step movement of the sequencing sealing means in response to a minimum of fluid flow rate through the inlet as well as large fluid flow rates. The check-flow control valve means moves the sequencing sealing means into position adjacent the outlets just as it moves downwardly out of the inlet. The force and weight of the fluid acts on the sequencing sealing means to seal a plurality of the outlets.

Claims9

Dependent claims

A multi-port sequencing valve comprising:

a housing having a central fluid receiving chamber, a chamber inlet, a housing inlet in fluid communication with said chamber inlet of said chamber, and a plurality of outlets disposed substantially on the side opposite of said central chamber from said chamber inlet, said outlets having a surrounding inner surface substantially concave in shape;
a sequencing outlet sealing valve means having at least one aperture disposed therethrough and a sealing surface for contact with said inner surface of said housing,
said outlet sealing valve means having a lower sloping engaging surface for engagement with said outlet surface to close at least some of said outlets, said lower sloping engaging surface of said outlet sealing valve means having a slope less than said surrounding inner surface of said housing to provide initial opening of said outlet sealing valve means in a non-fluid flow condition,
a stem means connected to said housing;
said stem means including a reciprocally movable portion with one end connected to the central portion of said outlet sealing valve means, said movable portion positioned centrally said housing;
a control valve means connected to said movable portion of said stem means and positioned on said movable portion to move into said chamber inlet to provide a barrier to fluid within said chamber inlet from passing out through said chamber inlet;
a biasing means connected to said movable portion of said stem means for rotating normally opening said outlet sealing valve means and positioning said control valve means within said chamber inlet when fluid stops flowing through said chamber inlet into said chamber, fluid flow through said housing moves said control valve means out of said chamber inlet and said outlet sealing valve means into sealing engagement with said inner surface of said housing,
a cam means connected to said stem;
said cam means including a first portion connected to said housing and a second cam portion connected to said stem for engagement with said first portion to rotate said outlet sealing valve means during reciprocal movement of said movable portion of said stem;
said first portion connected to said housing and being removably connected to said housing whereby said first portion of said cam means may be easily replaced.

7 more elements

A water-operated selector valve comprising:

a housing including a main portion with a plurality of outlets adjacent one end of the housing, a centrally located inlet in the housing to direct the outward flow of fluid in a generally uniform pattern toward said plurality of outlets, said housing including a generally concave internal surface about said outlets.
an outlet sealing valve means having at least one aperture,
a stem connected at one end to said sealing valve means and disposed centrally in the housing, said stem having an axis that passes through the inlet, said stem connected to said housing for rotating and reciprocating in respect to said housing,
an inlet valve means connected to said stem for movement toward and away from said centrally located inlet by fluid passing from said centrally located inlet toward said outlets for moving said sealing valve means against said outlets,
a stem biasing means for positioning said inlet valve means in relation to said central inlet and moving said sealing means away from said outlets when no fluid is flowing through said housing,
said sealing valve means movable toward and away from the outlets by the fluid passing from said centrally located inlet toward said outlets for sealing all said outlets except those in juxtaposition with the apertures, said sealing valve means rotatable with said stem to move said aperture from outlet to outlet,
a cam means including at least one sequencing cam and at least one cam follower, said can means connected to said housing and to said stem to control the movement of said stem, said sealing valve means and said inlet valve to position said aperture,
said sealing valve means includes a generally concave surface facing said centrally located inlet for supporting the weight of incoming fluid to aid in downward movement of said sealing valve means and an opposite convex sealing surface.
