Abstract

The oil reservoir is part of a system operating an electrical switch by means of a differentially operated piston, switch operation being via a valve determining which side of the piston is pressure exerted, obtained from a pressure pump and reservoir. The oil return path is through a second reservoir in which the pressure differentials can be of the order of 300 atmospheres. The transient nature of this pressure change can result in vapourisation of the oil in the reservoir and the general degrading of the oil condition. Baffle plates at the input end of the reservoir provide step by step reduction of this oil pressure.
