Method of cooling a pneumatically actuated cylinder/piston unit

摘要

The exhaust air from the cylinder/piston unit (1) is used for cooling its cylinder (16). For this purpose, the exhaust air released by an upstream control valve (2) attached to the unit (1) is passed through an annular expansion chamber (30) which eccentrically surrounds the cylinder (16) and is defined by a sleeve (31) of porous material. <IMAGE>
