A valve device includes: a housing; a flow channel extending in the housing; a shaft mounted rotatably in the housing, and having a screw bore having a shoulder; a flap, fastened to the shaft, the flap influencing a flow cross section in the flow channel; a screw having a collar, the screw fixedly attaching the flap to the shalt a drive driving the flap via the shaft; and a valve seat in the flow channel, the valve seating having a seal arranged on a radially circumferential edge of the flap, the seal being in contact with the valve seat in a closed position of the flap such that the shaft penetrates the flap at an angle. The collar contacts the shoulder such that, when the screw is tightened firmly, a transmission of force from the collar to the shaft takes place via the shoulder.

Disclosed is a wheeled vehicle. The wheeled vehicle includes various features for operation by a rider, such as a throttle actuation assembly and various components for operation and manipulation of the vehicle.

The need for maintenance regarding wire stretching and position displacement between a throttle valve and an operation member is eliminated. A wire throttle adjustment device 1 is for performing open-close adjustment of a throttle valve by pull operation of a wire 2. The wire throttle adjustment device 1 includes an operation member 10 connected to an end part 2A of the wire 2 and configured to perform the pull operation of the wire 2. The operation member 10 includes an action part 11 that is elastically deformable by the pull operation of the wire 2 in a fully-opened state of the throttle valve. The action part 11 includes an elastically-deformable elastic arm part 12 configured to swing together with the operation part 15 and extending from the pivotally-supported part 14, and the end part of the wire 14 is connected to a tip part of the elastic arm part 12.

An altitude fuel limiter and method for controlling an engine using the same is provided. The altitude fuel limiter includes a torque screw sleeve extending from an inboard end to an outboard end. The torque screw sleeve has an interior surface defining a central bore extending axially within the torque screw sleeve. A plunger is disposed within the central bore and moves axially between a first position and a second position. A plunger regulator senses ambient pressure and is coupled with the plunger to axially displace the plunger toward the inboard end of the torque screw sleeve to the first position in response to sensing an ambient pressure that is below a predetermined pressure. The predetermined pressure may be associated with non-compliant altitudes and the plunger limits fuel delivered to the engine when displaced to the first position.

A reaction force control system for a pedal that is configured to stably operate a vehicle in which an operating mode can be shifted between normal and one-pedal modes, without requiring a complicated operation, and without disturbing a driver. An operating mode is selected from a one-pedal mode in which a drive force and a brake force are controlled by manipulating an accelerator pedal, and a normal mode in which drive force is controlled by manipulating the accelerator pedal, and the brake force is controlled by manipulating the brake pedal. Reaction force applied to the accelerator pedal is increased for a predetermined period of time when shifting from one of the operating modes to the other one, and thereafter the reaction force is adjusted in accordance with a position of the accelerator pedal in the other one of the operating modes.
