DOOR DE TEMPERATUUR BEDIENDE AFSLUITER.

摘要

A temperature responsive valve includes an elongated body having an axial passageway with a cylindrical valve rod extending therealong and actuated by a thermally responsive push pin. The valve rod includes an axial aperture extending through one end with a radial port remote from such end. A spool-shaped spacer is sealably fitted in the passageway and circumscribes the rod valve defining an inner chamber continuously communicating with the radial port of the valve rod and defining an outer chamber communicating with an inlet port. The spacer includes an aperture formed therethrough and coupling said inner and outer chambers. The push pin actuates the valve rod to selectively engage a ball valve positioned at one end of the body which communicates with an exhaust port. Radially extending inlet and outlet ports communicate with the passageway and inner and outer chamber through the valve rod and spacer for selectively coupling supply means to an actuation cylinder or exhausting the cylinder to atmospheric pressure as a function of temperature detected by the thermally responsive push pin.
