Abstract

The piston (1) is mounted on rod (5) and fixed by a nut (6) on a stack formed by a retaining disc (7), a thrust washer (8), a centering washer (9) which has radial slots (9a) and a valve washer (3). Permanent passages are obtained by interposing an intermediate washer (10) between the thrust washer and the centring washer. This intermediate washer has a diameter a little greater than the centring washer and has slots (10a) aligned with the centring washer slots. The intermediate washer diameter is about 5-20% greater than the centring washer diameter. This results in no wear on the piston, only on the disc (7), thrust water (8), centring washer (9) and intermediate washer, and there are permanent passages through the washer stack to the piston passages.
