Multi-fluid flow control device
First Claim
1. A multi-fluid flow control device comprising an elongate body with front and rear ends, oppositely disposed upper and lower sides and oppositely disposed lateral sides, a liquid conducting chamber within the rear portion of the body, liquid inlet and outlet openings entering the exterior of the body and communicating with the chamber, means to connect the liquid inlet and outlet openings with liquid supply and delivery means, an elongate bore opening entering the front end of the body and communicating with the chamber, water inlet and outlet ports entering sides of the body and communicating with the bore opening between the ends thereof, means to connect the inlet and outlet ports with a water supply means and with a water delivery means, an elongate valve part with front and rear ends and a water transfer passage with upstream and downstream ends between its ends, front and rear seals carried by the valve part forward and rearward of the water transfer passage and sealing between the valve part and the bore opening, said valve part is shiftable longitudinally in the bore opening between a rear position where the rear seal is positioned in the bore opening between the chamber and the water inlet and outlet ports and the upstream and downstream ends of the passage are aligned with the inlet and outlet ports and a forward position where the ends of the passage are out of alignment with the water inlet and outlet ports and the rear seal is positioned forward of the water inlet port and communication is established between the water inlet port and the chamber through that portion of the bore opening between the inlet port and the chamber.

Abstract
A multi-fluid flow control device comprising an elongate horizontal body with front and rear ends, a fluid-conducting chamber in the rear end portion of the body, fluid inlet and outlet openings communicating with the chamber, an elongate bore in the body between the chamber and the front end thereof, and, water inlet and outlet ports communicating with the bore; an elongate valve part with front and rear ends and a transverse water transfer passage with laterally opening upstream and downstream ends and slidably engaged in the bore and shiftable longitudinally therein from a rear position where the upstream and downstream ends of the passage register with the inlet and outlet ports to direct water entering the inlet port out through the outlet port and a forward position where said ends of the passage are out of register with said ports and water entering the inlet port is directed rearwardly through the bore in and into the chamber; a central opening in the valve part between the front end thereof and the passage therein, an elongate valve stem with front and rear ends threadedly engaged in the central opening and having a valve head at its rear end to enter the passage and a manually engageable operating knob at its rear end.
