Abstract

Oil from the pump is supplied to the valve block via a port leading to two spring loaded ball valves. One of these leads to the discharge port to the jack and the other, with higher preset spring load bypasses fluid to the reservoir if excess pressures occur. For controlled return of fluid from the jack, with the pump stopped, an electromagnet actuates a needle valve, opening a passage to the reservoir port. Another passage leads oil from the jack via a spring loaded autorestrictor valve to the needle valve and then to the reservoir. A preset flow restrictor is fitted between the jack and the automatic flow regulating valve.
