    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.

    专利说明:

    This invention relates to internal combustion engines. Valves are known for a liquid-cooled internal-combustion engine with a circulating medium, such as oil, containing a rod with longitudinal coolant supply and exhaust channels and a plate connected to it, provided with annular internal grooves and rapial channels associated with the longitudinal channels 1. Liquid; internal communication of the valve, contributes to intensive heat removal from the most heated parts of it, including the plate, which is exposed to the most adverse effects of mountains their gases .. However, with a different cross section of internal communications that predetermine a deviation in the flow rate of the liquid, the amount of heat removed from the individual elements of the valve pins and tails can change, which reduces the cooling intensity and adversely affects the durability of the valve in a particularly poor condition The valve plate is connected in a known manner to the stem. The purpose of the invention is to increase the cooling efficiency of the valve, especially at the plate level, to increase its durability. This goal is achieved by the fact that the cross sections of the longitudinal channels of the rod, as well as the radial channels and colthic groove of the valve plate are constant and equal to each other. The drawing shows the proposed valve. The valve for an internal combustion engine with a liquid-cooled circulating medium, such as oil, contains a rod 1 with longitudinal channels 2 of the coolant inlet and outlet 3 and connected to the impeller 4, equipped with an annular internal groove 5 and radial channels 6 and 7 connected with the longitudinal channels 2 and 3. The cross sections of the longitudinal channels 2 and 3, the radial channels 6 and 7, and the annular groove 5 are constant and equal to each other.
