Abstract

The blade is fixed by means of three bolts to the light alloy head. A mobile blade is bolted to the fixed blade. A bolt is fixed by a small plate in which is a semi-circular hole and screw. The case contains two cylindrical, operating compartments divided by a central diaphragm. In each compartment slides a piston fixed to the same rod joined to the mobile blade by means of a link. The rod has a lengthwide, axial hole with T-shaped outlet. The top compartment contains a spring and a rubber damper. The top piston is fixed by a single forked disc, and the bottom piston by a single nut. A plastic base is screwed to the bottom of the case and has a compressed-air flow regulating valve operated by a lever.
