Pressure control device for reducing fluid pressure of hydrogen in fuel cell for motor car, has pressure reducing valve whose output side is connected with input side of safety shutoff valve whose output side is connected with outlet

摘要

The control device has a housing (2), an inlet (3), an outlet (4), and a pressure reducing valve (5). The inlet is connected with an input side (6) of the pressure reducing valve. An output side (8) of the pressure reducing valve over a hole (9) in housing is connected with an input side (10) of safety shutoff valve (7), while the output side of safety shutoff valve is connected with outlet. A piezoelectric actuator (16) is equipped for controlling the pressure reducing valve.
