Abstract

A seal structure for the joint section between path forming members, configured in such a manner that a seal member is disposed between a first path forming member and a second path forming member, the seal member having a seal section mounted in an endless mounting groove provided in the surface of the first path forming member which is joined to the second path forming member. The seal member (12) is configured so as to integrally have: the seal section (12a); ear sections (12b) protruding sideward along a joint surface (10) from the portions of the seal section (12a) which are separated from each other in the peripheral direction; and protrusions (12c) respectively protruding from the ear sections (12b) in the direction opposite the direction toward a second path forming member (6) so as to be perpendicular to the joint surface (10). The joint surface (10) is provided with: recesses (21) adapted to respectively house the ear sections (12b) and connecting to the mounting groove (19); and press-fit holes (22) which each have one end open to the recess (21) and which allow the protrusions (12c) to be press fitted therein. The configuration facilitates the mounting of the seal member, prevents a mounting error, and provides a uniform tightening allowance over the entire periphery of the seal section.

Summary of the invention

The problem that invention will solve

But, the structure of the projection of the outer circumferential side wall of mounting groove and the periphery Elastic Contact of sealed member is made as disclosed in by above-mentioned patent documentation 1, and make in the structure that contacts with inner circumferential wall and the periphery wall surface elastic of mounting groove in the projecting projection of the inner circle wall of sealed member and multiple positions of periphery wall as disclosed in by above-mentioned patent documentation 2, in the bossed part of configuration not for the space that sealed member is dodged to radial direction, under the bonding state of pair of channels forming member, at the bossed part of configuration and other parts place, the magnitude of interference of sealed member is different, be difficult at the impartial magnitude of interference of the circumference setting of sealed member.And, by the structure disclosed in above-mentioned patent documentation 3, cannot visual pushed position be pressed into recess to protuberance, cannot be confirmed whether to be pressed into exactly, the assembling therefore cannot getting rid of sealed member is completely slipped up.

The present invention completes just in view of the foregoing, its object is to the sealing configuration that a kind of passage forming member connecting part is provided, assembling error can be avoided while the facilitation of installation realizing sealed member, and the magnitude of interference of the complete cycle equalization of sealed department can be guaranteed.

For solving the technological scheme of problem

In order to reach above-mentioned purpose, the present invention is a kind of sealing configuration of passage forming member connecting part, the passage communicated with each other under bonding state is respectively arranged with in the first and second passage forming member be bonded to each other, the mating face engaged with second channel forming member of first passage forming member is provided with mounting groove, described mounting groove is annularly compassingly set at the opening end towards described mating face of the passage of first passage forming member, sealed member has been clamped between the first and second passage forming member, described sealed member is installed on described mounting groove and has the sealed department be annularly connected, the fisrt feature of the sealing configuration of described passage forming member connecting part is, described sealed member has with forming as one: described sealed department, ear, described ear is outstanding to side along described mating face from multiple positions circumferentially spaced apart in sealing portion, and teat, described teat is outstanding to the side contrary with second channel forming member from described ear respectively in the direction orthogonal with described mating face, the described mating face of first passage forming member is provided with recess and press-in hole, described recess is connected to hold described ear respectively with described mounting groove, one end of described press-in hole is to described recess opening to be pressed into by described teat, described press-in hole is with the end, in the side of described teat, gap slot is formed in the length range of this teat, described gap slot extends along the pressing direction be pressed into described press-in hole.

Further, on the basis of the structure of fisrt feature, the second aspect of the present invention is, the thickness of described ear is formed than thin at the thickness in the direction orthogonal with described mating face under the bonding state of the first and second passage forming member of described sealed department.

And, first or second feature structure basis on, the third aspect of the present invention is, to be provided with from outside side, sealing portion outstanding described ear at two positions circumferentially spaced apart of described sealed department continuously.

In addition, the throttle body 5 of mode of execution is corresponding with first passage forming member of the present invention, and the suction tude 6 of mode of execution is corresponding with second channel forming member of the present invention, and the first mating face 10 of mode of execution is corresponding with mating face of the present invention.

Invention effect

In accordance with a first feature of the invention, sealed member has with forming as one: sealed department, and it is annularly connected; Multiple ear, they are outstanding to side from multiple positions circumferentially spaced apart in sealing portion; And teat, described teat is given prominence to from described ear, and be provided with on the described mating face of first passage forming member: continuous print mounting groove, it is for installing sealed department; Recess, described recess is connected with mounting groove to hold ear respectively; And press-in hole, one end of described press-in hole is to recess opening to be pressed into by teat, therefore, by teat is pressed into press-in hole, can prevent sealed member anti-loaded, or sealed member is arranged on the such mistake in the position that circumferentially offsets to install, and sealed member can be stably remained on first passage forming member being arranged on by sealed department under the state in mounting groove, can prevent sealed member from coming off from first passage forming member in conveyance and transport.And, owing to visually can confirm to carry out on one side the press-in operation that teat be pressed into press-in hole, therefore, it is possible to suppress generation operation to be slipped up.And, because ear is outstanding to side from sealed department, therefore, be provided with the part of multiple ear and other parts place, the magnitude of interference of sealed department can not be caused different, thus can at the magnitude of interference of the circumference setting equalization of sealed department, in addition, gap slot is formed in the side of teat, described gap slot extends along the length range of the pressing direction be pressed into press-in hole with the end at teat, therefore, when to press-in hole press-in teat, can prevent from becoming air-tight state between the closed end of press-in hole and teat and vent plug occurring, the lifting of assembling performance can be realized.

And, according to second feature of the present invention, the thickness of ear is formed thinner than the thickness under the bonding state of the first and second passage forming member of sealed department, therefore, ear can not impact the magnitude of interference of sealed department, thus can guarantee the magnitude of interference of the complete cycle equalization of sealed department.

And according to third feature of the present invention, ear gives prominence to from the outside side, two positions circumferentially spaced apart of sealed department, and therefore, can with the hands hold ear when assembling sealed member and install, assembling operation becomes easy.
