Abstract

1,182,999. Belt or chain tensioning devices. FIAT S.p.A. 6 March, 1968 [13 March, 1967], No. 10934/68. Heading F2Q. A belt or chain tensioning device comprises a piston 16 slidably mounted in a housing 12 and resiliently urged into contact with a pivoted shoe 8 engaging the belt or chain by a spring 25 located in a bore 24 in a stem 19 which is adjustably clamped in the housing 12 by a split ring 20 and screw-threaded cap 21 so that its axial position may be varied in order to vary the tension of spring 25. A washer 28 is urged by a spring 27 against an enlarged head portion 23 of stem 19, and excessive movements of the piston 16 are cushioned by the spring 27 through the engagement of a shoulder 29 in the piston 16 with the washer 28. The device is applied to a cam-shaft drive of an internal combustion engine.
