Piston movement adjustment device for assembling piston rod into pressure tube, has adjustable-force control mechanism with temperature dependent trigger device, to control movement of piston rod in gas-filled pressure tube

摘要

An adjustable force control mechanism (19) has a temperature dependent trigger device (21) and a pawl (25). Piston rods (11,13) are arranged axially-movable within pressure tubes (7,9), respectively. A pawl operated by a bimetal spring (23) connects the piston rod (13) and controls its movement, according to temperature.
