The camwheel is rotatable about a camwheel axis.

The cam wheel can be controlled to rotated at different angular velocities.

The rotation of the camwheel about the camwheel axis engages the carrier and moves the combiner between the stowed position and the display position.

The device includes a cam wheel (20) to which are connected one or more suction arms (22).

Eighteen cylinder-enclosed pistons (20, 20-1 through 20-18) are positioned in a circular plane about the cam wheel (12) such that the radius of the circular plane and the cam wheel are coplanar.

In one implementation, the engine (10) includes a cam wheel (12) mounted to an output shaft (14).

A drive mechanism including a gear cam wheel sequences movement of the secondary pawl to open and reset the latch.

The length of the towel which can be withdrawn is limited by a ratchet (43) and a pawl (44).

A combiner positioning system for a head-up display includes a carrier and a camwheel.

The camwheel is rotatable about a camwheel axis.

The camshaft (7) according to the invention has a camshaft body (5) and a camshaft wheel (1) which is attached to the camshaft body (5).

The retractable wheel assembly can include a cammed linkage arm operatively coupled to a retractable wheel.

In the case of said camshaft (1), a gearwheel (5) is attached to a camshaft tube (3).

The front gearbox system comprises a polygonal cover (313), a transmission gear (308), a crankshaft gear (307), an idler gear (303), an air inlet camshaft gear (302) and an exhaust camshaft gear (306).

The mechanism consists of two units: gear transmission for operating the camshaft (A) and of the camshaft with adjustable cams (B).
