摘要：The invention provides an inexpensive and simple mechanical spring system
which automatically compensates for variations in the clearance gap in the valve-actuatingmechanism of internal combustion engines, whereby considerably to lengthen the timean engine can be in operation before manual adjustment of the clearance gap becomesnecessary. The system comprises at least one tin metal disc (20) located between aconvex surface (21a) in contact with the centre of one face of the disc (20) and an annularsurface (22a) in contact with the periphery of the other face of the disc (20), movement ofthe surfaces (21a, 22a) together deforming the disc (20) around the convex surface (21a)to produce a spring force which increases at a variable rate until it exceeds the valvespring (14) loading and the valve (12) opens. The mechanism is initially adjusted so thatthe spring deflection is approximately one half the deflection required to overcome thevalve spring loading.
