Abstract
843,294. Diesel-acting two-stroke engines. DORNFELD, R., and DORNFELD, E., [trading as DELMAG-MASCHINENFABRIK R. DORNFELD]. Jan. 31, 1958 [Feb. 8, 1957], No. 3342/58. Class 7(2). [Also in Group XXVI] In a diesel ram cooling air is supplied from the chamber 119 below the piston to cooling passages 112 in the cylinder head and/or conduits 124 in the piston. The ram cylinder 11 is provided with cooling ribs 111 and the piston controls a combined exhaust and scavenging air port 114 arranged so that when it is uncovered on the down stroke of the cylinder cooling air flowing therethrough into chamber 119 is directed towards the bottom of the piston. The cooling spaces 124 in the piston are open to chamber 119 and connected to atmosphere through passages 125, 126 in the piston rod. Cooling air is delivered to the space 112 in the cylinder head and thence to atmosphere through a passage 113, cooling fins 163 on the cylinder head forming a flow restriction therein. The motion of the ram cylinder causes cooling air to be alternately forced out from chamber 119 to atmosphere through the passages 125, 113 and sucked back in therethrough. The fuel tank 13 and injection pump 15 are mounted in the cylinder head.
