Abstract: A method comprises receiving a displacement signal generated by a sensor, the displacement signal generated by the sensor in response to detecting movement of a piston from a retracted position in a cylinder toward an extended position in the cylinder. The method further comprises generating, in response to receiving the displacement signal, a valve control signal to be communicated to a valve located on a vacuum line connecting a vacuum source to a vacuum port of the cylinder. The valve control signal causes the valve to move from a first position in which a vacuum pressure is applied to the cylinder via the vacuum port to a second position in which atmospheric pressure is applied to the cylinder via the vacuum port.

Abstract translation: 一种方法包括：接收由传感器产生的位移信号，响应于检测到活塞从气缸中的缩回位置到气缸中的延伸位置的运动而由传感器产生的位移信号。 该方法还包括响应于接收到位移信号而产生阀控制信号，该阀控制信号将传递到位于将真空源连接到气缸的真空端口的真空管线上的阀。 阀控制信号使得阀从其中通过真空端口向缸体施加真空压力的第一位置移动到第二位置，在该第二位置，大气压通过真空端口被施加到气缸。

Abstract: A system includes a cylinder and a piston that moves within the cylinder from a retracted position to an extended position. A vacuum port facilitates application of a vacuum pressure to the cylinder that results in a vacuum force being applied to the piston, which causes the piston to move toward a top end of the cylinder to the retracted position. A spring member applies a spring force to the piston when the piston is in the retracted position. The spring force offsets at least a portion of the vacuum force. A sensor generates a displacement signal in response to detecting movement of the piston from the retracted position toward the extended position. A control unit receives the displacement signal generated by the sensor and generates a valve control signal to be communicated to a valve located on a vacuum line connecting a vacuum source to the vacuum port.
