Abstract: A valve device includes a housing, a valve member, a valve seat member, a fixing member for fixing the valve seat member to the housing, and a housing-side seal portion. The housing has a valve chamber, and a housing-space inner wall forming a housing space communicating with the valve chamber. The housing-side seal portion blocks a flow of fluid between the valve seat member and the housing-space inner wall. The valve seat member has a tubular portion and a flange portion connected to the tubular portion. The flange portion is interposed between a facing surface of the housing-space inner wall and the fixing member in an axial direction. The fixing member is fixed to the housing-space inner wall in an airtight state. The housing-side seal portion is made of a rubber material and is interposed between the flange portion and the fixing member.

Abstract: A valve device includes a shaft, a valve body, and a housing including a valve opening. An outwardly facing surface of the valve body is out of contact with the housing and a valve-facing surface is in contact with the housing in a fully closed state in which the valve body closes the valve opening. A valve seal surface includes a first valve seal surface protruding in a valve closing direction and a second valve seal surface recessed in a valve opening direction. A first seal distance in a radial direction from an outer diameter end of the first valve seal surface to a rotation axis is shorter than a second seal distance in the radial direction from an outer diameter end of the second valve seal surface to the rotation axis. The first valve seal surface and the second valve seal surface each have at least a curved surface.

Abstract: A link apparatus includes a cam plate, a lever and an accommodation member. The cam plate has a cam groove. The lever has a roller engaged with the cam groove and a pin which is inserted through a center of the roller so that the roller is rotatably supported on the pin. The accommodation member accommodates the cam plate and the lever. The accommodation member and the pin have a distance “A” therebetween. The roller has a thickness “B” along an axial direction of the pin. The value of the distance “A” is smaller than the value of the thickness “B”.

Abstract: A valve device increases or decreases a flow rate of EGR gas. The valve device includes a housing, a bypass valve body, an EGR valve body. The housing includes: a first upstream passage into which the EGR gas cooled by an EGR cooler flows; a second upstream passage into which the EGR gas that bypasses the EGR cooler flows; a junction connected to each of a gas-flow downstream of the first upstream passage and a gas-flow downstream of the second upstream passage; and a downstream passage connected to the first upstream passage and the second upstream passage via the junction. The bypass valve body is provided in the second upstream passage. The EGR valve body is provided in the downstream passage.

The housing includes a first upstream passage into which the EGR gas cooled by an EGR cooler flows, a second upstream passage into which the EGR gas that bypasses the EGR cooler flows, and a downstream passage connected to the first upstream passage and the second upstream passage, and provided downstream with respect to the first upstream passage and the second upstream passage. The bypass valve body opens and closes the second upstream passage. The EGR valve body is provided in the downstream passage and rotates around an EGR valve axis to open and close the downstream passage.

Abstract: Shaft is rotationally driven, and a valve body rotates together with the shafts and has a cylindrical surface on an outer peripheral surface. A housing has a valve chamber in which the valve body is rotatably accommodated, and the valve chamber has an opening opened or closed by the valve body. The outer peripheral surface is provided to be in a non-contact with the housing. The valve body has a valve seal surface for closing the opening by abutting on a predetermined part set in the housing when the opening is fully closed, and the valve seal surface is directed in the circumferential direction. The valve body has a core metal made of a metal, and the shafts are provided on both ends of the core metal, and a valve seal surface is made of a resin.

Abstract: A valve device includes a valve housing, a valve member, a limiter portion and a contact portion. The valve housing includes an upstream-side flow passage, which is communicated with an intake passage, a receiving space, which is communicated with an EGR passage, a valve chamber, which communicates between the upstream-side flow passage and the receiving space, and a valve-housing-side seal portion, which is placed around an opening that communicates between the upstream-side flow passage and the receiving space. The valve member includes a valve-member-side seal portion, which blocks communication between the intake passage and the EGR passage when the valve-member-side seal portion contacts the valve-housing-side seal portion. The rotation of the valve member is limited when the contact portion contacts the limiter portion.
