Abstract

Improvements introduced in a refrigerated plate valve for an internal combustion piston engine, an internal cavity in which a primary cooling medium is enclosed, which has been designed to effect the evacuation of heat from the valve plate on stem thereof; characterized by the fact that a device for the evacuation of heat has been implemented within the valve stem, which is provided with transfer surfaces for heat, which have been provided to be bathed by a secondary cooling medium, which during operation is introduced into said stem and which serves to effect heat evacuation from this same stem.
