Abstract

A freezeless wall hydrant for delivery of hot or cold water from a single discharge conduit has first and second fluid inlet pipes in parallel spaced relation. The pipes have forward and rearward ends and are connected respectively to sources of hot and cold pressurized water. A laterally extending fluid conduit member connects the forward ends of the first and second fluid inlet pipes and is in communication therewith. A fluid closure valve is located in the rearward ends of each of the first and second fluid pipes. A check valve is in each of the pipes forwardly of the fluid closure valves and is capable of permitting fluid flow in the pipes in a direction from the closure valve, but prevents fluid flow towards the closure valves. A valve rod having forward and rearward ends rotatably extends through the laterally extending fluid conduit and through the forward ends of the first and second inlet pipes and has one end operatively connected to the check valves in the rearward ends of the fluid inlet pipes. A handle is located on a protruding forward end of the valve rods to permit the manual movement of the rods to open or close the fluid closure valves. A fluid exit conduit has a rearward end in communication with the laterally extending fluid conduit and extends forwardly and downwardly and terminates in a hose threaded portion. A check valve is located in the fluid exit conduit to prevent fluid flow therein only towards the forward end of the fluid exit conduit.

A freezeless wall hydrant for delivery of hot or cold water from a single discharge conduit, comprising,

elongated first and second fluid inlet pipes in parallel spaced relation and having forward and rearward ends,
a laterally extending fluid conduit member between and adjacent to the forward ends of the first and second fluid inlet pipes, and being in fluid communication therewith,
a fluid closure valve in the rearward ends of the first and second fluid inlet pipes,
a check valve in each of the first and second fluid inlet pipes forwardly of the fluid closure valves and being capable of permitting fluid flow in the pipes in a direction from the closure valve, but preventing fluid flow towards the closure valve,
a valve rod having a forward end rotatably extending through the laterally extending fluid conduit and thence through forward ends of the first and second fluid inlet pipes and being operatively connected to the check valves in the rearward end of the fluid inlet pipes,
a handle in a protruding forward end of the valve rods to permit the manual movement of the rods to open or close the fluid closure valves,
a fluid exit conduit having a rearward end in connection with the laterally extending fluid conduit, and a forward end terminating in a hose threaded portion,
a check valve in the fluid exit conduit to permit fluid flow therein only towards the formed end of the fluid exit conduit,
the rearward ends of the first and second fluid pipes being connected to sources of hot and cold water, respectively rearwardly of the fluid closure valves.
