ABSTRACT:
The cage for the valve seat is provided with cooling ducts which are uniformly spaced about the cage. Alternating ducts are used as coolant supply ducts while the remaining ducts are used as exhaust ducts. The ducts are arranged to uniformly cool the cage and valve seat. Suitable cross ducts are used to achieve a uniform distribution of the coolants supplied to the cage as well as a uniform removal of a coolant.
