Abstract

Improvements introduced in a mushroom-type valve cooled by circulation of a refrigrant fluid, such as oil, and whose valve is composed of a rod, an annular head forming two pieces assembled with each other, and comprising two substantially longitudinal channels, respectively return flow of the cooling fluid, machined in the valve stem, in communication with two substantially transverse channels, respectively round-trip, machined in the valve head, in communication in turn with an annular chamber machined in said head, characterized by the combination of the head assembly on the stem by indirect welding along the whole of its interface, and by the substantially uniform free passage section of the cooling fluid throughout the valve, both in its tail and in his head.
