Abstract

A pneumatic chuck comprises a casing (1) divided by a piston (2), oriented along its longitudinal axis, into an inlet chamber (3) and a pumping chamber (4). The inlet chamber (3) is connected to a compressed air source through an air supply pipe (6) passing through an axial opening in the piston (2). The pumping chamber (4) is connected to the inlet chamber (3) through an annular gap (7) between the air supply pipe (6) and the piston (2). At the moment of its evacuation the pumping chamber (4) is connected to the atmosphere. The cross-sectional surface (10) of the piston (2), facing the pumping chamber (4), is larger than that of the end-face surface (11) of the piston (2), facing the inlet chamber (3) but smaller than that of the end-face surface (12) of an annular projection (8) on the piston (2), facing the pumping chamber (4), an additional chamber (9) being formed on the inlet chamber (3) side by said projection and by the casing (1).
