The more recently developed parallel hydraulic intensifier also uses oscillating pistons to compress water.
2.
A "'hydraulic intensifier "'is a hydraulic machine for transforming pressure into a reduced volume at higher pressure.

The hydrokinetic brake system was successful and reliable on the APT-E and was retained for the APT-P with a number of design improvements from the lessons learnt on APT-E . However, as an energy-cutting measure, the hydraulically actuated friction brakes used for low speed were modified to be fed by a passive hydraulic intensifier rather than a hydraulic power pack.
