In operation, when the piston is below the exhaust ports 10, the pressure in the lower chamber 5 is greater than that in the upper chamber 4 so that the piston is caused to move upwardly. During its upward movement, it closes the exhaust from the upper chamber and opens it to the lower so that the continued upward movement is due to inertia. The buildup of pressure in the upper chamber stops the piston and causes it to start its downward movement. Near the end of the downward movement towards the tool 3, the exhaust is opened to the upper chamber. In Fig. 5 (not shown) porous elements (21c, 22c) cover the feed passages. In Fig. 6 (not shown) the exhaust ports are spaced axially such that the exhaust is never entirely closed off by the piston during its movement and starting is ensured. Further, to aid starting, inserts may be provided in the feed passages, Figs. 3 and 4 (not shown), these being connected by ducts to the opposite chambers to which the feed is being directed; the inserts in Fig. 3 ensure that upon starting, air passes from the lower chamber through a duct (13a) to a series of holes (12a) surrounding the feed passage (7a) for reducing the air supply to the upper chamber; the inserts in Fig. 4 consist of elastomeric sleeves which are contracted by the pressures in the opposite chambers to reduce the effective cross-sectional areas of the feed passages.
