Patent ID: 8613396

Claim:
A temperature-operated water flow valve for selectively ejecting naturally heated water stored in a hose, said temperature-operated water flow valve comprising: a hollow body having axially offset proximal and distal open ends respectively, said body further having an internal temperature; and a temperature-activated plunger release mechanism seated inside said body and intermediately positioned between said proximal and distal open ends respectively; wherein said temperature-activated plunger release mechanism automatically reciprocates along a linear travel path as said internal temperature rises above a threshold internal temperature and falls below the threshold internal temperature respectively; wherein said temperature-activated plunger release mechanism is automatically opened and closed during said reciprocation along said linear travel path such that water is respectively permitted and prohibited to egress said distal open end of said body; wherein said temperature-activated plunger release mechanism comprises a first retention plate having a plurality of apertures formed therein for permitting water to flow downstream towards said distal open end, said first retention plate further having a shell integrally formed therewith and axially extending towards said distal open end; a wax pellet located within said shell; a first piston dynamically interfitted within said shell and directly abutted against said wax pellet; a stem connected to said first piston; a valve seat inwardly protruding towards a center of said body such that a maximum diameter of said valve seat is less than a maximum diameter of said body; a second piston connected to said stem and removably conjoined to said valve seat; a deformably resilient spring fixedly attached to said second piston; and a second retention plate engaged with said spring and located at said distal open end of said body, said second retention plate having a plurality of openings formed therein for permitting water to egress said body.
