Abstract
The invention relates to a mushroom-type valve cooled by cooling fluid circulation for an internal combustion engine wherein the terminal face of the end portion of the stem is aligned flush with the corresponding face of the valve head and forms the central portion thereof, and the assembling of the head is carried out by brazing on the stem along the whole of their interface.
Claims19
A mushroom-type valve for an internal combustion engine comprising an assembled stem and annular head joined together along a common interface therebetween, the valve having a plurality of non-concentric fluid circulation conduits interconnected together by an annular passage formed in the annular head, said conduits and said annular passage being of uniform free cross-sectional area.
A mushroom-type valve for an internal combustion engine comprising an assembled stem and annular head, the valve having a plurality of non-concentric fluid circulation conduits, the head coaxially surrounding an end portion of the stem, the end portion extending through the head to a terminal face of the head, the head having a cylindrical bore of a given diameter in complementary engagement with the end portion of the stem, the head having a cylindrical counter-bore of a diameter greater than the given diameter, the counter-bore being in complementary engagement with the end portion of the stem and the head terminal face being in aligned flush contacting relationship with a corresponding terminal face of the stem, with the conduits comprising a plurality of passages extending longitudinally within the stem, each longitudinal passage terminating in a passage transverse to the longitudinal passages, the transverse passages being interconnected by an annular passage, said longitudinal, transverse and annular passages being of uniform free-cross sectional area.
