Method and device for control of the passive movement of pneumatically moved slides in low-temperature refrigerating machines

摘要

To control the passive movement of a pneumatically driven slide 3 in a low-temperature refrigeration machine of the separate-circuit type, the coolant gas is pressed through a narrow duct 11 inside the pneumatic cushion so that the gas exerts a viscous friction force or damping effect on the wall of the duct 11 as it flows through the duct 11 (Fig. 2). <IMAGE>
