Abstract

1276985 Cam-shaft drives GENERAL MOTORS CORP 19 April 1971 [2 April 1970] 24515/71 Heading F1B I C engine has an overhead cam-shaft driven by a toothed belt which passes round toothed pulleys on the crank-shaft, and cam-shaft the belt having a plurality of longitudinal V-grooves in its back surface which engage a correspondingly grooved pulley mounted on the drive-shaft of a coolant pump. The belt 52 is driven by a pulley 24 on the crank-shaft and drives a pulley 26 secured to the cam-shaft. The belt also passes over a pulley 38 which is mounted on the coolant pump shaft and also carries a fan. The pump shaft is rotatably mounted in a housing 28 which is held to the engine block by bolts 46 which pass through slotted holes 42 in the housing. The cavity which receives the pump impellar is large enough to allow lateral movement of the pump to adjust the belt tension. The tension is adjusted so that the pump and fan are driven continuously during normal operation, but the belt slips under extreme loads e.g. as caused by rapid engine acceleration.
