Field of the Invention The present invention relates to a gasket for sealing used in a gap between a housing and a lid opposed to the housing. The present invention relates to a gasket which is mounted in a seal groove formed in a housing and which can sufficiently cope with a portion where a high pressure is applied or a variation in the gap is large. 2. Description of the Related Art Conventionally, a rubber gasket such as an O-ring is used as a flat type sealing gasket which is loaded in a gap between a housing and a lid and is vertically sealed vertically. However, if the variation between the housing and the lid is large, the O-ring cannot follow and there is a possibility that sufficient sealing performance may not be obtained. [0003] As a gasket to be used in a portion where the gap between the housing and the lid is largely varied, FIG.
As shown in Fig. 4, the cylindrical housing 31 has an annular seal groove.
A seal 32 is provided and an annular rubber gasket 34 is mounted in the seal groove 32. The above-mentioned annular gasket 34
Have projecting portions 36 and 37 projecting obliquely upward and inward from upper and lower ends of a side portion 35 having a flat surface abutting on an inner peripheral wall 33 of the seal groove 32, and the inner periphery of the gasket 34 is curved. A pressure receiving surface 38 having a shape of a circle is formed. The side portion 35 of the gasket 34 is brought into contact with the inner peripheral wall 33 of the seal groove 32 formed in the housing 31,
The gasket so that the protrusions 36 and 37 at the upper and lower ends of the gasket 34 are in contact with the lower surface of the lid 40 and the bottom surface 41 of the seal groove 32.
34 is mounted in the seal groove 32. As described above, when the gasket 34 mounted in the seal groove 32 receives a high pressure from the inside, the gasket 34
As a result, even if the seal groove 32 is chamfered, a part of the base of the protrusion 36 protrudes into the gap a. Cracks K etc. enter in between and eventually break down,
The sealability will be lost. SUMMARY OF THE INVENTION The present invention is directed to a gasket in which a crack due to protrusion does not occur even in a region where the above-mentioned high pressure is applied or where the gap between the housing and the lid is large, and a sufficient sealing property is obtained. The purpose is to provide. [0007] A gasket according to the present invention comprises:
In order to achieve the above-mentioned object, a gasket body made of an elastic material such as rubber having an upper lip and a lower lip is baked on the inner peripheral side of the metal reinforcing ring, and a radial direction is provided at a lower portion of the metal reinforcing ring. It is characterized in that an annular projection protruding outward is formed integrally with the gasket main body, and when the gasket is mounted on the housing, the gasket is attached to the housing by the annular projection. It is characterized in that it is positioned so as to be positioned in the radial direction and movably in the axial direction. According to the gasket of the present invention, a gasket body made of an elastic material such as rubber having an upper lip and a lower lip is baked inside a metal reinforcing ring, and the gasket body is provided below the metal reinforcing ring. Since the annular projection protruding outward in the radial direction was formed integrally with the gasket main body, the gasket was mounted on the housing, and when the lid was opposed, the upper lip of the gasket was attached to the lid. The lower lip abuts on the housing to seal the portion, and the gap between the lid and the housing is sealed in the axial direction of the gasket, so that it is baked on the inner peripheral side of the metal reinforcing ring. The gasket body made of an elastic material such as rubber does not protrude into the gap. Therefore, even if the variation in the gap between the housing and the lid is large, the variation is not affected, and the gasket is supported by the metal reinforcing ring even when a high pressure is applied from the inside. When the gasket is mounted on the housing, the annular projection is formed with a margin so that the gasket can move in the axial direction of the housing, and is assembled to the housing. When the body is opposed to the housing, the upper and lower lip of the gasket body made of an elastic body such as a rubber of the gasket abuts on the lid and the housing, and the annular projection is formed by the elastic reaction force of both lips of the gasket body. Slides on the inner peripheral wall of the housing, and the entire gasket can be stopped when the elastic reaction force is balanced. An embodiment of the present invention will be described with reference to the drawings.
1 and 2, a gasket 1 is formed by baking a gasket main body 5 made of an elastic material such as rubber having a required thickness and having an upper lip 3 and a lower lip 4 on the inner peripheral side of a metal reinforcing ring 2. And molded. The upper lip 3 is provided at the tip of a protruding portion 6 protruding inward from the upper portion of the metal reinforcing ring 2 toward the upper side.
The metal reinforcing ring 2 is provided at the tip of an extension portion 7 extending obliquely downward inward from the inner peripheral side of the lower portion. An annular projection 8 is formed integrally with the gasket main body 5 made of an elastic material such as the rubber so as to extend radially outward of the lower portion of the metal reinforcing ring 2 and obliquely downward.
Reference numeral 9 denotes a thin film of an elastic body 5 such as rubber which is put on the upper surface of the metal reinforcing ring 2 at the time of molding, and reference numeral 10 denotes the metal reinforcing ring.
2 is a thin film of an elastic body such as rubber provided on the outer periphery at the time of molding. The gasket 1 is used to seal a gap 13 formed between a cylindrical housing 11 and a lid 12 opposed to the housing 11,
In the gasket 1, the annular projection 8 of the gasket 1 is assembled to the inner peripheral wall 14 of the housing 11 with a tight margin S. The tight margin S is such that the gasket 1 is assembled to the annular housing 11. It is sufficient that the tightening allowance be such that the play in the radial direction when the gasket 1 is removed and the gasket 1 is prevented from falling off during assembly. Therefore, the gasket 1 can be easily moved via the annular projection 8. This means that when the gasket 1 is loosely fitted when the gasket 1 is assembled to the housing 11, the gasket 1 falls off the housing 11, and when the gasket 1 is tightly fitted, the gasket 1 is tightly fitted. When the gasket 1 is fixed to the inner peripheral wall 14 of the seal groove 15 of the housing 11 and the lid 12 is opposed to the gasket 1, the gasket 1 is located between the housing 11 and the lid 12.
Since the gasket 1 cannot be stopped when the gasket 1 is in a well-balanced state due to the elastic reaction force of the two lips, the above-mentioned interference S is set. Conventionally, this type of gasket is sealed with a gasket made of rubber alone, but in this embodiment, a metal reinforcing ring 2 and an elastic material such as rubber which is baked on the metal reinforcing ring 2 are used. The gasket 1 is constituted by the gasket main body 5 and the gasket 1 is attached to the inner peripheral wall 14 of the seal groove 15 of the housing 11 via the annular projection 8 so as to be movable. When the lid 12 is opposed to the housing 11, the gap 13 between the housing 11 and the lid 12 is sealed by the gasket 1 having the metal reinforcing ring 2. As described above, in this embodiment, since the gap 13 between the housing 11 and the lid 12 is sealed by the gasket 1 having the metal reinforcing ring 2, the pressure from the inside is reduced. The metal reinforcing ring 2 is sufficiently supported even by acting on the gasket body 5 made of an elastic material such as rubber, which is supported by the metal reinforcing ring 2 and is baked on the inner peripheral surface of the metal reinforcing ring 2. Will be protected. Therefore, the gasket main body 5 is provided in the gap between the housing 11 and the lid 12.
Since the gasket main body 5 does not enter the gasket 13, there is no possibility that the gasket main body 5 will be cracked. In this embodiment, the gasket 1
When the lid 12 is attached to the housing 11, the upper lip 3 and the lower lip 4 of the gasket main body 5 abut on the lid 12 and the housing 11.
The projection 6 provided with the lower portion and the extension portion 7 provided with the lower lip 4 are opposed to each other with an interference when the cover body 12 is opposed to the housing 11, so that the projection portion 6 and the extension portion are provided. The gasket 1 moves in the axial direction due to the elastic reaction force of 7, and comes to rest in a balanced state.At this time, the gasket 1 of this embodiment can be moved in the axial direction by the annular projection 8 as described above. The gasket mentioned above
The axial movement of 1 can be easily performed. As described above, in this embodiment, when the housing 11 and the lid 12 are opposed to each other, the seal is provided with the metal reinforcing ring 2, so that the pressure on the gasket 1 is reduced by the metal reinforcing ring. The ring 2 is received so as not to affect the gasket main body 5 made of an elastic material such as rubber which is baked on the inner periphery of the metal reinforcing ring 2 at all. Therefore, in the present embodiment, the gap between the housing 11 and the lid 12 is
Regardless of the magnitude of 13 or the level of pressure, good sealing performance can always be obtained. According to the gasket of the present invention, a gasket main body made of an elastic material such as rubber having an upper lip and a lower lip is baked inside a metal reinforcing ring, and the metal reinforcing ring is formed. Since the annular projection protruding outward in the radial direction is formed integrally with the gasket main body at the lower part, the gasket of the present invention is assembled to the housing, and when the lid is opposed, the upper part of the gasket main body is formed. The lip abuts on the lid and the lower lip abuts on the housing to seal the area.At this time, the gap between the lid and the housing is sealed with a gasket provided with a metal reinforcing ring. The gasket body made of an elastic material such as rubber which is baked on the inner peripheral side of the metal reinforcing ring does not protrude into the gap. Therefore, even if the variation in the gap between the housing and the lid is large, the gasket is not affected by the variation, and even if a high pressure is applied from the inside, the gasket is supported by the metal reinforcing ring and the elastic body such as rubber. Has no effect. Further, when the gasket is mounted on the housing, the gasket is mounted on the housing via the annular projection with an interference so that the gasket can move in the axial direction of the housing. When the body is opposed to the housing, when the upper and lower lips of the gasket abut against the lid and the housing, the gasket can be easily moved in the axial direction due to the elastic reaction force of the elastic gasket body.
