摘要： In a pneumatic reciprocatory actuator (1 - 3) of the kind comprising a cylinder (1) which defines a forward-motion chamber (5) and a return-motion chamber (7), and a piston (2) which is reciprocable in the cylinder (1) and separates the forward-motion chamber (5) and the return-motion chamber (7), a start stroke forwardly is initiated by admission of a gaseous operating fluid from an inlet port (4) into the forward-motion chamber with both the forward-motion chamber (5) the return-motion chamber (7) initially at zero pressure. The operating fluid is also passed from the inlet port (4) into the return-motion chamber (7) during the start stroke until a back pressure of a predetermined magnitude (4) has been produced in the return-motion chamber (7). Then the return-motion chamber (7) is automatically closed by a pressure control valve unit (20, 21), whereby the return-motion chamber (7) will form a cushioning chamber for cushioning the movement of the piston (2) in the forward direction, thereby preventing piston overspeeding during the start stroke.

摘要： Pneumatical piston-cylinder unit, named "air-cylinder", having a cylinder (1) in which an air piston (4) with a tubular piston rod (5) is reciprocatable, actuated by compressed air from two main air channels (18, 19), and in which the air cylinder (1) comprises an integrated hydraulic control system (6) having an actuation means (8) which is fixedly mounted in the air cylinder (1) for creating a flow of hydraulic fluid through the hydraulic control means (6) when compressed air is present in the main air channels (18, 19) and for stopping the flow of hydraulic fluid and thereby the possibility for the air piston to move in case there is no compressed air in said main channels (18, 19). A piston (34) and a cylinder (28) of the hydraulic control means (6) are displaceable an adjustably long distance in relation to each other for thereby making it possible to open and close, respectively, a larger or smaller hydraulic fluid passageway thereby controlling the moving speed of the air piston (4) while maintaining the air pressure. The air cylinder comprises means (15, 16, 40) for setting the piston stroke of the air piston (4) and the exact location of the axial piston movement.
