Abstract

544,260. Valves. JOHNSON & SONS, Ltd., C. H., HARTLEY, J. A., and PHILLIPPOVIC, J. W. Dec. 9, 1940, No. 7434. [Class 7 (vi)] [Also in Groups XXI and XXIII] In an internalcombustion rammer or pile driver having a free piston cooperating with a loose piston rod attached to a striker foot, for example as described in Specifications 293,228, 313,516, [both in Class 124], 347,492, and 484,814, [Group XXIII], the inlet valve a in the cylinder head and the exhaust valve b in the piston are in the form of discs operated automatically without springs. Exhaust ports 2 in the cylinder are also controlled by the piston.
