Abstract
628,843. Hydraulic machines. ANDERSON, J. Feb. 3, 1947, No. 3173. [Class 69 (ii)] In a machine tool or other machine having an hydraulic feed operated by oil circulated under pressure by a pump, a thermosensitive device, sensitive to the temperature of the oil being circulated, operates as the temperature rises to pass part of the oil to a body of oil which supplies make-up oil to that being circulated, the amount of make-up being such that the temperature of the circulated oil, and therefore its viscosity, is kept substantially constant. As shown, part of the oil circulated by a pump b through a relief-valve e, pipe l, chamber h and pipes m o, back to a sump i, is passed as the 'oil temperature rises by a valve g operated by a thermosensitive device f, to a part of the sump which communicates through a restriction j with the part from which the pump draws. A jack a forms part of the hydraulic feed of a machine tool and to operate the jack a control-valve c is opened to connect the relief valve e through a metering valve to the righthand end of the jack. To reverse the jack the control valve is operated to connect the righthand side of the jack piston to a pipe n<SP>1</SP> leading to the sump.
