RECEPTACLE FILTER FOR FILLING HYDROGEN

摘要

PURPOSE: A receptacle filter for high-pressure hydrogen charge is provided to manufacture a filter by sintering and heating the powder of the powder particle such as copper or copper alloy and include the filter to the receptacle, thereby conveniently filtering the foreign material in hydrogen charge. CONSTITUTION: A metal powder filter member(14) of conic shape is formed into one to a ring-type support member within a receptacle body. In a hydrogen charging, a hydrogen is flown in smoothly into a gap space(32) from the entrance of the receptacle body. At the same time, the contact surface of the hydrogen on the surface of the metal powder filter member. An foreign material within the hydrogen is filtered in the filter member. The foreign material continuously passes through the minute pores and check valve(20) within the filter member.
