Abstract

1328644 Adjusting valve clearance DEFENCE SECRETARY OF STATE FOR 16 Nov 1971 [1 Dec 1970] 57093/70 Heading F1B [Also in Division F2] Device for adjusting valve clearance between a cam 28 and stem 15 of a valve 14 comprises a bucket-type cam follower 24 having a bore 23 which receives a piston 22 resting on the end of the valve stem and a block of non-compressible material 31 situated between the blind end of the bore 23 and the end surface of the piston 22. There are radial bores 32 in the cam follower, each bore containing a plunger 37, the position of which can be adjusted by a screw to alter the volume of the recess containing the block 31 and thereby the clearance between the cam 28 and the piston 22. The cam follower is held against the cam by a spring 29 which bears on a washer 30. To lock the screws in their adjusted position, there are balls 39 which are pressed by the spring 29 and washer 30 against flats formed on the screws. In a modification the screws are formed with recesses which receive the balls.
