摘要： An actuator, comprising a cylinder (1), an actuator piston (2) displacably arranged in the cylinder (1), a pressure fluid circuit having a channel (3) mouthing in said cylinder (1), an indirectly electrically controlled first valve body (4), arranged in said channel (3) for controlling a flow of a pressure fluid in said channel (3), and a second valve body (5), arranged in or at said channel (3) to open and close the channel (3), the second valve body (5) being a member fixedly connected to the actuator piston (2), and the first valve body (4) and the second valve body (5) being arranged in series with each other in said channel (3). The actuator further comprises an electrically controlled three-way valve ( 18) that is arranged to alternately open for a pressure fluid flow from a high pressure source (HP) and a pressure fluid flow from a low pressure source (LP), chosen pressure fluid flow being arranged to act against and admit displacement of the first valve body (4).

摘要： A pneumatic actuator, connected to a pressure fluid circuit (6) that has a high pressure side and a low pressure side, an actuator cylinder (8, 9), an actuator piston (10, 11) provided in said actuator cylinder (8, 9) and displaceable between a first position and a second position, an actuator chamber (12, 13), delimited by said actuator cylinder (8, 9) and the actuator piston (10, 11), wherein the volume of said actuator chamber decreases upon a displacement of the actuator piston (10, 11) from the second to the first position to the first position, a spring means provided to drive the actuator piston (10, 11) from the second position to the first position, and means (25) provided to maintain or establish a communication between the low pressure side and the actuator chamber (12, 13), during a displacement of the actuator piston (10, 11) from the second position towards the first position, and at the same time to keep the communication between the high pressure side and the actuator chamber (12, 13) interrupted. The pneumatic actuator comprises means (25) provided to interrupt said communication between the low pressure side and the actuator chamber (12, 13) before the actuator piston (10, 11) reaches the first position.
