TH62033B - Engine depressurization set - Google Patents

Abstract

DC60 (14/03/57) in the engine depressurization kit, where the camshaft supported rotates by the cylinder head. It is provided with an exhaust cam and where the pressure reducing weight is supported. It can be rotated with the camshaft via the pressure relief bolts which are parallel to the camshaft. There is a pressure reducing cam which is also connected. Where the pressure relief cam can be extended from The circular part of the base of the exhaust cam The depressurization kit has been compactly built. By reducing the size of the cylinder head to be smaller The depressurization bolt 55 is arranged inside the periphery of the raised section 40b of the exhaust cam 40 as viewed from the axial direction of the camshaft 30 in the engine deceleration kit, where The camshafts which are supported rotatable by the cylinder head It has been provided with an exhaust cam as well where the pressure reducing weight is supported. It can be rotated with the camshaft via the pressure relief bolts which are parallel to the camshaft. There is a pressure reducing cam which is also connected. Where the pressure relief cam can be extended from The circular part of the base of the exhaust cam The depressurization kit has been compactly built. By reducing the size of the cylinder head to be smaller The depressurization bolt 55 will be arranged on the inside of the periphery of the Section for overhang 40b of the exhaust cam 40 when viewed from the axial direction. Of camshaft 30

Claims (3)

1. Engine depressurization kit where the camshaft (30), which is rotatable by the cylinder head (13), is provided with the exhaust cam (40) with a base circle (40a), which It is formed in the shape of a circular arc centered on the axle of the camshaft (30) and the elevated portion (40b) extending outward of the base circle (40a) and connected to Both ends in the circumferential direction of the base circle section (40a), in such a way that the exhaust cam (40) opens the exhaust flaps (25) with the overhang section (40b) and where the pressure relief cam. (57), which can be extended from the base circle (40a), is connected to the depressurization weight (56), which is rotatable by the camshaft (30) via the depressurization pin ( 55), whose axis is parallel to the eccentric shaft (30), where the depressurization bolt (55) is arranged inward, the periphery of the Section for overhang (40b) when viewed from the axial direction of the camshaft (30). 2. Engine depressurization set according to claim 1, where: one end of the camshaft (30) is rotated by the cylinder head (13) through the support bearing (37). ; And pressure reducing weight (56), which has a washer (73), which is inserted between it, and The support bearing (37) is arranged between the support bearing (37) and the exhaust cam (40) and is supported as a cantilever with the exhaust cam (40). 3. Engine depressurization set according to claim 2, where a number of overhangs (74,75), provided in contact with washers (73), are formed in an overhang. The surface which is opposite to the washer (73) of the depressurization weight (56).
