摘要： A fixing shaft portion of a valve shaft is fixed to a throttle valve at first and second locations by first and second fixing members. A first bearing includes an inner race fixed to a first rotatable shaft portion of the valve shaft, and an outer race fixed to a valve body. A second bearing includes a slidable portion axially slidably fitted to a second rotatable shaft portion of the valve shaft and a fixing portion fixed to the valve body. A linear expansion coefficient of the throttle valve and a linear expansion coefficient of the valve body are set to be larger than a linear expansion coefficient of the valve shaft in an axial direction. A first distance measured from a center point of the throttle valve to the first location is larger than a second distance measured from the center point to the second location.

摘要： A hot gas valve has a housing, in which a gas duct is formed with an inlet and an outlet, and a valve device for controlling the fluid flow through the gas duct. The housing has at least one cooling duct for liquid cooling of the housing, wherein the gas duct is shielded with respect to the housing by means of a thermal shield, which consists of a material which has a greater thermal stability than the material of which the housing consists. The valve device has a closure body situated in the gas duct, which closure body is held on a valve shaft mounted in the housing by means of at least one bearing. The bearing may consists of a material having good thermal conductivity. The valve shaft is sealed by an elastomer shaft sealing ring on the side of the bearing facing away from the gas duct.

摘要： A valve assembly includes a valve housing defining a bore with a first axis extending along a length of the bore, and a valve shaft partially disposed within the bore along a second axis that is perpendicular to the first axis. The valve assembly additionally includes a valve plate coupled to the valve shaft and disposed within the bore, and a restricting device including a stop member and an engagement member. The stop member extends from the valve housing and presents a stop surface. The engagement member extends from the valve shaft and presents an engagement surface. At least one of the stop surface and the engagement surface is non-parallel with the second axis. The at least one non-parallel surface engages the other of the stop member and the engagement member and biases the valve shaft axially along the second axis.

摘要： A passive exhaust valve assembly includes an exhaust conduit that has a first pipe section attached in generally axial alignment with a second pipe section. The end portion of the first pipe section includes a circumferential segment disposed within the end portion of the second pipe section to form an overlapping interface. The end portions of the first and second pipe sections each include a flange protruding radially outward from the respective first or second pipe section, whereby the flanges engage with each other to form an axle seat therebetween. A support shaft extends laterally across an interior volume of the exhaust conduit and rotatably engages the axle seat. A valve plate is coupled to the support shaft within the interior volume of the exhaust conduit for moving relative to the exhaust conduit between open and closed positions.
