Valve i.e. pressure regulating valve with e.g. 3/3-way functionality, has pressure equalization chamber in fluid communication with valve chamber, where annular surface of valve chamber is located between valve seats

摘要

The valve (1) has two valve elements (5, 6) movable relative to each other and relative to a valve housing (2) in an axial direction of a main axis (7). A valve chamber (45) is arranged around a valve seat (36) and connected to a valve port (12). Another valve chamber (46) is arranged between the valve seat and another valve seat (27), and connected to another valve port (13). A pressure equalization chamber (62) is in fluid communication with the latter valve chamber, where an annular surface (56) of the latter valve chamber is located between the valve seats.
