The sheave rotates around a drive axis.

The invention concerns a variable pump or hydraulic motor with a drive axis with a first axis of rotation and first plungers connected to the drive axis and rotatable around the first axis of rotation.

Flywheel-powered motion's machine, which includes, prime motion's axle (1)» rotating by muscular or other motion power and transmits motion, to final motion axle ( G).

A coupling means (8) for the drive shaft of prophy angles (10) includes an upper drive shaft assembly (12) with a finger-type clutch (14), a main drive shaft (18) with a clutch receptacle (20), and a drive shaft clamp (22).

A vertical-axis wind turbine is described, of the type comprising a tower (2, 2'), a vertical motor shaft (5) that connects the rotor (20) to an electrical generator (4).

A tip turbine engine assembly (8) includes a fan (32) rotatable in a fan plane (22) about an engine centerline (112).

The rotating part includes two end axles (10a, 10b) and one live axle (12) which is connected between the two end axles.

A coupling means (8) for the drive shaft of prophy angles (10) includes an upper drive shaft assembly (12) with a finger-type clutch (14), a main drive shaft (18) with a clutch receptacle (20), and a drive shaft clamp (22).

The motor is provided with supply pistons (2) axially displaced by an oblique plate (10) with respect to the motor shaft (5), said plate being orientable by a controlling device with respect to a pivoting axis.

A rotary valve for controlling air supply in an inflatable device comprises a first rotor (11) and the second rotor (12) driven by motor (13) with a drive pulley (14) fixed directly onto its drive spindle (15).

The electromotor includes a principal axis (1) and a motor.

After the spindle motor (15) is assembled, the outer surface of the spindle motor (15) can be washed.

The sheave rotates around a drive axis.

The case extends about an axis of the engine.

A spindle motor (601) is installed on the motor base (6).
