Solenoid valve seat and method of making same |
摘要 |
An improved, air tight valve seat for a pneumatic brake system is achieved by using a plastic valve seat that is coined by the valve member. The valve member is a harder material, for example metal, than the thermo-plastic valve seat. The valve member is brought to an elevated temperature less than the melting point of the valve seat. The valve member engages the valve seat, coining the desired surface of the valve seat to conform it to the valve member. The heated valve member then remains in the valve assembly after coining.
