ABSTRACT:
An apparatus for creating gas flow cycles comprises a housing defining a chamber (80) provided with gas functions and a passage (76) for connection with an equipment to be tested. A unit movable in the housing throttles the passage. The position of the unit (75) is controlled by electrical signals received from a control unit. Sensors supply electrical signals representative of the position of the mobile assembly and of the pressure. The junctions are provided for connection with gas sources at different pneumatic pressures through solenoid valves.
