Abstract:
To provide a valve that is opened during filling processing of a refrigeration or heat circuit, and can work even after the filling.SOLUTION: A valve comprises: a housing 12 which has a connection point 14 for insertion into a connection device, the connection point having a passage opening 21 which connects at least one feed opening 22 and at least one outlet opening 24; and a valve seat 26 which corresponds to the passage opening 21 and can be closed by a valve closing member. The valve closing member can be transferred by a drive part or a medium pressure into a working position, in which the valve closing member is lifted with respect to the valve seat 26 and releases the passage opening 21. A securing element 41 is provided which holds the valve-closing member, relative to the valve seat 26, in a filling position 44, in which the valve closing member is lifted with respect to the valve seat 26 and releases the passage opening 21. After the initial transfer of the valve-closing member from the filling position 44 into the working position, the securing element 41 can be moved into a disengagement position relative to the valve-closing member, and thereafter the valve-closing member can be transferred to a closing position.SELECTED DRAWING: Figure 1
