Abstract

974,944. Treating charge and ventilating crankcases. S. SMITH & SONS (ENGLAND) Ltd. Oct. 8, 1963 [Oct. 16, 1962], No. 39216/62. Heading FIB. Crankcase gases are returned to the induction pipe through a valve mechanism comprising a first valve 18, Fig. 1, which is closed when the engine is stationary but opens when the engine is running and a second valve 28 which is normally open but tends to close as the crankcase pressure falls. The outlet 15, Fig. 1, is connected by pipe 16, Fig. 3, to the induction pipe 17, and outlet 30 by pipe 30a to the crankcase 31, the air inlet of which, through the valve cover 33, is restricted by a filter 35. Valve 18 remains closed during starting of the engine to avoid diluting the fuel-air mixture but is opened by suction immediately the engine starts. Valve 28 is controlled by a diaphragm 26 subject to the pressure in the crankcase; as the crankcase pressure decreases, the valve 28 is moved towards orifice 14 to throttle the flow of crankcase vapours and maintain an approximately constant suction in the crankcase, e.g. within the range of 1 to 5 inches of water. In Fig. 4, the valve cover inlet 36 is sealed and the valve cover connected through a flame trap and restricting device 43, 44, to the carburetter filter 40 to which the atmospheric side of the valve controlling diaphragm is connected by pipe 53. The flame trap 43, 44, contains wire gauze 48 and a rubber disc 49 which normally seats on a plate 45 so that the air flow into the crankcase is restricted by orifices 51. If a blow back past the pistons raises the crankcase pressure, the plate 45 lifts to allow pressure release through large orifices 52. In Fig. 7, the valve mechanism 10 is mounted on the oil filter opening of the valve gear cover 33, a passage 61 opening into the valve cover and an outlet 10 being connected to the induction pipe 17.
