Document Type and Number:
Japanese Patent JP7446422
Kind Code:
B2
Abstract:
The invention relates to a connection fitting (102) for a valve coupling and/or measuring or test coupling (2) for fluid systems for detecting working pressures of fluid media, the coupling (2) comprising a coupling bushing (6) which is subject to operating pressure in the installed state and which has a connection part (16) and a borehole (10) in which a spring-loaded and mechanically actuatable non-return valve (32) is arranged, the valve body (18) of which, in the non-actuated state, is supported on a valve seat (52), the connection fitting (102) having an opening pin (114) having a more particularly circular, closed contact surface for the valve (32) and at least one passage (118) extending laterally to the contact surface, through which passage a connection can be established between the connection fitting (102) and the valve coupling and/or measuring or test coupling (2).
