The center portion surrounds the insert component. The outer peripheral portion includes a toothed portion and a toothless portion. The weld-line portion is formed in at least one of the center portion, the connecting portion and the outer peripheral portion at a location which is on a radially inner side of the toothless portion. The rib-shaped portion is formed in at least one of the center portion, the connecting portion and the outer peripheral portion at a location which includes the weld-line portion. The rib-shaped portion has a wall thickness that is larger than a wall thickness of another circumferential portion.

A waste gate assembly for a turbocharger includes a valve member formed by a valve shaft and an arm attached to an end of the shaft, the arm defining a through bore, an inner surface of the through bore defining an arm groove therein. A poppet for the valve has a pin whose outer surface defines a pin groove. A generally polygonal retaining ring of elastically deformable wire is installed partially in the arm groove and partially in the pin groove to retain the poppet on the pin, thereby attaching the poppet to the arm of the valve member. An anti-rotation feature prevents relative rotation of the poppet about the pin axis. Vertices of the retaining ring are in the arm groove, while sides of the retaining ring are in the pin groove. Once the retaining ring is pre-installed in the arm groove of the arm, the arm can be assembled to the poppet by a push-to-connect process.

A cold regulating valve for a heat exchanger system of an aircraft propulsion system, where the cold regulating valve includes an open frame which delimits an opening, two shutters with an external convex shape slidably mounted on the open frame between a closed position and an open position, a mechanism linked to the shutters and mobile between a first position and a second position, and wherein the mechanism moves the shutters from the closed position to the open position when it moves from the first position to the second position and vice versa, and an actuator acting on the mechanism to move it from the first position to the second position and vice versa. The specific embodiment of the cold regulating valve generates a low drag when the shutters are in a closed position.

A control device for a WG actuator includes a feedback control unit for performing feedback control on the WG actuator in such a way that the position of a shaft detected by a position sensor gets close to a target position, and an abnormality detecting unit for providing an instruction to move the shaft in an axial direction for the feedback control unit, and for detecting an abnormality in the WG actuator on the basis of a result of a movement of the shaft, the movement being detected by the position sensor while the feedback control unit performs the instruction.

Disclosed is an air mix valve including: a wall having at least three openings; and at least one airflow-regulating device. The airflow-regulating device includes: at least two shutters placed in the internal volume of the valve, at least one aerodynamic shutter of which is arranged with respect to one of the openings so as to be able to receive an airflow passing through this opening, and a linking mechanism between at least two shutters. Each of the shutters is arranged and guided so as to be able to be caused to move with respect to the wall. At least one airflow-regulating device, named aero-controlled regulation device, is mounted to be freely movable under the effect of aerodynamic energy from airflows passing through the openings.

A number of variations may include a product comprising: a linkage system comprising: a first and second lever; a first interconnecting component and second interconnecting component operably connected to the first and second levers; a link bar having a first end with a first opening for receiving the first or second interconnecting component, and providing a clearance between the first opening and the first or second interconnecting component and; a second end with a second opening for receiving the first or second interconnecting component and providing a clearance between the second opening and the first or second interconnecting component; and a biasing device having a first and second end for engagement with the first and second interconnecting components and at least one section to allow for increasing or decreasing its length, wherein when the first or second end of the biasing device is engaged with one of the first or second interconnecting component and an external force is applied to one of the first or second ends of the biasing device to cause the biasing device to either increase or decrease in length to allow engagement with one of the first or second interconnecting component and to store energy, and wherein when the external force is removed from the biasing device, the stored energy of the biasing device provide a force that causes the first and second interconnecting components to move in a direction that overcomes the clearances between the first and second interconnecting components and the first and second openings of the link bar and provides contact between the first and second interconnecting components and the first and second openings of the link bar and wherein the contact is maintained by the force provided by the stored energy.

A valve having a housing in which three ducts that are connected to each another are arranged, one flap, which is mounted rotatably on a shaft is arranged in each of two ducts, an electric motor which drives a shaft by a gearing system, and a transmission mechanism, which drives the second flap depending on the movement of the first flap. On the shaft of the first flap, a cam disc is arranged, on the circumference of which a lever rests, which is connected in a rotationally fixed manner to the shaft of the second flap.

A valve gear box has a valve monitoring function. The valve gear box is for mounting to a valve that has a fluid passageway and a gate therefor, the gear box providing a gear driven link for moving the gate between open and closed conditions of the fluid passageway, the valve gear box being in a housing that has a mounting for permitting operative connection to the valve via a mounting flange of the valve. The mounting and the mounting flange have a valve monitoring sensor operatively positioned therewith, the sensor being settable in one state when the mounting and the mounting flange are in assembled relationship to each other but being configured to change from the one state if there is a separation of the fastened connection of the mounting and the mounting flange, whereby a change in state from the one state can be used to monitor a separation of the assembled relationship of the mounting and the mounting flange and trigger an alarm condition.

An electromechanical actuating drive (1) for a bulk-goods shut-off element, comprising an electric motor (2) and a control and drive electronics unit (3) associated with the electric motor (2), wherein the electromechanical actuating drive (1) comprises a mechanism for storing energy.

A vent assembly for use with a drinking vessel includes a flexible ventilation member configured to sealingly engage an opening in the drinking vessel and having an air passage extending therethrough, wherein the ventilation member is configured to allow an inflow of air when pressure within the drinking vessel enters a negative pressure state in relation to pressure outside the drinking vessel, wherein the ventilation member comprises one or more venting portions disposed within the air passage. A vent actuator is operably coupled to the ventilation member and configured to change a state of the ventilation member between a ventilation state and a closed state, wherein the vent actuator is integral with the ventilation member and configured to bring the ventilation member into the ventilation state upon contact with a cam portion.
