Embodiment Construction

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0041] (constitute)

[0042] The gasket of this embodiment is shown in FIGS. 1 and 2 . FIG. 1( a ) is a plan view showing the spacer 10 of the present embodiment, and FIG. 1( b ) is a plan view of a sub-plate constituting the spacer shown in (a). In addition, Fig. 2 is a cross-sectional view taken along the line A-A' in Fig. 1(a).

[0043] The gasket 10 of the present embodiment is an example of a gasket to be interposed between a joint surface of a cylinder head and a cylinder block of an internal combustion engine. The spacer 10 includes substrates 10', 10' stacked up and down, a sub-plate 10'' stacked between the substrates 10', 10', and a sub-plate 10'' between the substrates 10', 10' and the sub-plate 10'' Partially laminated backing plate 11 . Next, the configuration of each member will be described.

[0044] The substrate 10' is formed of a thin...

Abstract

The present invention provides a gasket which can uniformize the facial pressure on the thickened part more securely is to be provided. A gasket comprises a pair of base plates and stacked above and underneath, in which combustion chamber holes and bolt holes are bored, a doubling plate and shim plates intervene between these base plates. On this doubling plate, a second bead, which permits plastic deformation, extends in the circumferential direction of each combustion chamber hole. As the second bead is deformed according to the magnitude of the fastening load, the gasket height lowers where the fastening load is heavy and the facial pressure on the peripheries of combustion chamber holes is uniformized after fastening.

Description

technical field [0001] The present invention relates to a gasket, which is sandwiched between opposing joint surfaces of a cylinder block and a cylinder head constituting an internal combustion engine for sealing between the joint surfaces, for example, in motorcycles, automobiles, Industrial machinery, outboards, etc. Background technique [0002] As a laminate-type gasket, for example, there is a gasket shown in Patent Document 1. This is a technique in which the thickest part of the plate thickness is provided in the peripheral part of the combustion chamber hole, the design is designed to load a high load, the plate thickness is set small according to the necessary sealing performance, and the prevention of the cylinder head or the cylinder head is suppressed. Deformation of cylinder bore. That is, the purpose is to set the total plate thickness of the gasket to be the thickest at the peripheral portion of the combustion chamber hole, then at the bead portion on the ou...
