Abstract

916,004. Moulding-machines. MALCUS HOLMQUIST AB. April 26, 1961 [April 26, 1960], No. 15140/61. Class 83 (1). [Also in Group XXIX] The shaft 1 of a turnover moulding machine is turnable by a slide 3 which is reciprocated by two hydraulic cylinder devices 6, 7 actuated alternately, pressure air being applied to the respective cylinder directly above the liquid therein in order to act directly upon the liquid without an intervening piston. Pressure air is supplied to the cylinders through valve means 18, 19, and each cylinder includes a valve 13 which closes the hydraulic liquid outlet when the liquid level in the cylinder falls to a predetermined level. The air is evenly spread over the liquid level by a filter pipe 23, a baffle 21 and openings 22 and the filter pipe separates oil from the air passing said pipe when the cylinder is exhausting.
