Abstract (en)

[origin: EP2354546A1] The pump has an outlet valve assembly (11) provided with an electrical, hydraulic or pneumatic exhaust actuator (16'), where a part (17') of the actuator is fixedly mounted at a housing head. Another part (18') of the actuator is coupled, driven and movable with an outlet valve body (15). The actuator is arranged opposite to the valve assembly, so that a direction of movement of the movable part of the actuator caused by the actuator opposite to a movement direction of the mounted part of the actuator coincides with a direction of movement of the outlet valve body caused by a gas flow. The actuator is designed as a solenoid integrated with a return spring, or a piezoelectric actuator such as piezo-bending actuator, or a magnetostrictive actuator.
