Expansion valve

摘要

A pressure sensor 22 integrated into an expansion valve 1 is threaded into an opening 2a of a body block 2 accommodating a valve element 8 and a compression coil spring 9 for urging the valve element 8 toward a valve seat 7. A set response value for the expansion valve 1 depends inter alia from the spring load and is adjusted by the thread-in depth of the pressure sensor 22 in the body block 2. A variation of the thread-in depth changes the load of the compression coil spring 9 to change the set response value for the expansion valve 1
