Abstract:
A volume control device for a sealed reservoir for storing oil under pressure and which supplies oil to a power circuit. The volume control device has an expansible bellows assembly which contracts upon a predetermined increase of volume of oil in the reservoir to bring a rod into engagement with a ball check valve and unseat the valve for dumping of oil overboard from the reservoir. The dumping of excess oil from the reservoir is controlled by an increase of volume of oil in the reservoir, rather than an increase in oil pressure.
