Abstract
1282606 Valve loading TECUMSEH PRODUCTS CO 13 Nov 1969 [14 Nov 1968] 55536/69 Heading F1B In an I, C. engine including bias means for urging an inlet or exhaust valve 14, 16, Fig. 1 closed and for biasing the valve train into tracking relation with a cam 18, 20 the bias means includes a spring having a pair of arms extending from an arcuate or coiled portion one of which arms 80 is urged against a reaction surface 30 in the engine and the other 76 is engaged in a notch in the valve stem 46, 56. In a modification the valve guides (100, 102), Fig. 7 (not shown) are continued into the casing (28) to locate the spring portion 80, In a further modification each valve is closed by a hairpin type spring which has a loop located on the valve guide extensions, In a further embodiment the spring portion (80<SP>1</SP>), Fig. 12 (not shown) is engaged under an integral ledge (200) and held in place by an extension on the casing cover.
