清明作文the gas which is liberated from the oil into the metering space. The piston pump (50,52) is connected to and controlled by a controller (C). The metering space (22) compris a cylinder which accommodates a piston (58) which is connected to be moved by an actuator (62) which is connected to and controlled by the controller. The pressure detector (68) is provided which is responsive to the pressure in the metering space and is arranged to deliver a signal indicative of the magnitude of the pressure to the controller.
