Valve device

摘要

The hydraulic module (1A) of the valve assembly (1) has an entrance channel running past a valve body (3) engaging in a valve seat (4). The valve element (5) has a tapered portion (5A) leading to a narrow cylindrical portion (5B), surrounded by a spring (6). The spring pushes the valve element toward the open position. It is returned to the closed position by an electric actuator (1A) using a coil (16) and a ring-shaped yoke (17). There is a tolerance length for the spring and the valve element.
