Provided is a torsion tester which comprises a sealed case accommodating a decelerator, and an oil cup.

A method for lubricating mechanical units (110) contained in a sealed housing (100) is described, which includes providing an oil spray in the enclosure of said housing (100).

A hand-held scrubbing device (10) for cleaning a surface has a waterproof casing (20) having an interior area and an exterior area (22).

The invention relates to energy storage means that can be arranged in a fluid-tight housing in which an electric machine having a rotor and a stator is accommodated.

Temperature: 9° C. The exploration ends in the 6°C tight sump

An internal combustion engine, and an optional integrated electrical generator, both enclosed in a single waterproof and dustproof case.

A washing and cleaning device has a sealed housing in which there is an electrically driven device for generating vibration transferable from above the housing to the environment.

The fluid reservoir of the closed fluid circuit is disposed within an oil-tight housing, inside which the closed circuit is also enclosed.

Each drive transmission mechanism is housed in a watertight casing which also acts as the main strut for the wheel when in use.

To this end, the leakage oil collects in a tight trough located below the engine (1) and/or the gearbox (1').

The invention relates to a front-axle output of an automatic transmission with a front-axle spur pinion, said spur pinion being located in a sealed housing (15).

The invention further extends to a coupling assembly between an output shaft of a motor, and an input shaft of a machine, the motor being contained in a sealed housing.

This rotary compressor accommodates an electric motor and a compression mechanism that is linked to the electric motor via a rotary shaft in a sealed case.

An external discharging pipe (17) is opened to an intermediate chamber (S2) between a compressing portion (3) and the motor (2) in a sealed casing (1).

A helical compressor (10) has, inside a sealed casing (11), an electric motor (12) and a helical blade type compression mechanism (13) driven by the electric motor (12).

The machine for cutting mitre joints for the implementation of said assembly device (31) includes a sealed housing (1) provided with two circular saw blades (4, 5) perpendicular between themselves and operated by a single motor (2).
