The invention relates to a lateral channel compressor (2) comprising a lateral channel housing (24) and an impeller (10), which can rotate inside the lateral channel housing (24) and whose impeller blades (16) are mounted on an impeller hub (8).

The omnidirectionally moving wheel comprises a plurality of rotating bodies and a wheel.

The gas chamber in each impeller (13, 14) is connected to the corresponding gas chamber in the next impeller by means of a by-pass channel (7) located in the impeller.

Since the rotor is arranged in front of the guide apparatus (in the flow direction), the flow strikes the rotor first and does not strike the guide apparatus until after this, thus resulting in optimum flow conditions for the rotor.

The turbine has a larger axial runner wheel (2') and a reshaped runner ring (34) peripherally extending around the runner wheel.

During the rotation of the impeller (13, 14), the sealing liquid in each impeller and housing stage forms a rotating ring which hugs the stationary (2a to 2c) or rotating housing.

The impeller is rotatably supported by the cylinder.

The other spur wheel contacts the other most mobile spur wheel which engages with a wheel seated on a drive shaft.

A simulated wheel device (1) is provided with a simulated wheel (11) and a movable base (12).

Said wheel comprises a hub (5) and a central axle opening (6) that houses an axle (10), the latter (10) being held in the axle opening (6) with the aid of a sleeve (8).

The invention relates to a running wheel (1), for example for a steering roller or support roller.

A sealing area (29) having an impeller-side sealing surface (31a) is located in the area of the impeller hub (8) between the impeller (10) and the lateral channel housing (24).

A magnetic machine has a rolling wheel and a pulley.

The assembly comprises a movable member for supporting the wheel.

Anti Skid Wheel: The wheel must be an anti-skid wheel.
