Patent DE-3007665-A1 (DE)
Inventor: SCHLEGEL RAINER DIPL ING
IPC: F16J15/38
Filed: 1980-02-29
Abstract: A secondary sealing element for axial seal rings, is resistant to stresses due to temperature, pressure, vibration, corrosion, swelling and shrinking. This sealing element is produced of non-rubber-type elastic and non brittle material and its shape, in cross-section, consists of a ring, with a pair of arms to give it an elastic reaction. The double-arm ring forms three radial-type sealing surfaces and is completely locked into a chamber. Special material with low static friction and higher thermal conductivity than rubber material is used. Furthermore the dissipation of heat, produced by the axial sliding rings, will be increased through the double contact area to the shaft by the arms in comparison to an O-ring, and through a wear-resistant and non-corrosive layer on the shaft having at least the thermal conductivity of the basic material.

Title: Pneumatic impact drill with reciprocating piston - has striker in cylinder between piston and anvil holding bit
Inventor: SEKIZAWA MASAAKI
IPC: B25D11/00
Filed: 1980-10-27
Abstract: The pneumatic impact drill avoids undesirable shocks once the work has been pierced, having an open-ended cylinder with a vent port (23) in one side. A piston (16) reciprocating in the rear end of the cylinder generates pressure alterations, being driven by a power unit (15,17). An anvil (20) moves to and fro in the cylinder and has at the forward end a chuck (7) detachably securing a bit (8) for drilling through the work (W), and the pressure alterations cause a striker to reciprocate (32) in the cylinder between piston and anvil. The port is situated at a point before that where the striker hits the anvil, so that it is shut off by the striker as it moves forward and a pressure rise is generated between striker and anvil. A non-return valve (24) in the cylinder sidewall discharges the air subjected to this pressure rise, so forming a closed chamber between striker and anvil afterwards.
