A surface treatment device for applying a surface treatment to an inner surface of a hollow engine shaft extending longitudinally along a shaft axis and having an axial shaft length to be treated. The device includes a supply of a surface treatment agent and an elongated rod extending from a proximal end to a distal end with an applicator disposed at the distal end. The elongated rod is insertable inside the hollow engine shaft. An applicator is disposed at the distal end of the elongated rod and wetted with the surface treatment agent. The applicator is engageable with the inner surface of the hollow engine shaft for applying the surface treatment agent to the inner surface of the hollow engine shaft. A pair of markers are disposed on the elongated rod and axially spaced apart from one another at a first axial distance corresponding to the axial shaft length.

A varnish injector assembly for an electric motor includes an injector nozzle, a varnish reservoir fluidly connected to the injector nozzle, and a filament extending from the varnish reservoir. The filament is configured to direct varnish from the injector nozzle to a slot of a stator core.

The invention concerns a device (11) for applying abradable material, designed to apply abradable material to a surface of an annular casing (1) of a turbine engine, wherein the casing extends along a longitudinal axis and the device (11) comprises a support (12, 13) equipped with first guiding means (14) capable of guiding the support (12, 13) in relation to a casing (1) in a radial direction in relation to the axis of the casing, the support (12, 13) being equipped with second guiding means (16) capable of guiding the support (12, 13) in relation to the casing (1) in an axial direction, an application roller (20) being pivotally mounted in relation to the support (12, 13) in the axial direction and adjustment means (22, 23) allowing adjustment of the position of the roller (20) in relation to the first guiding means (14), in the radial direction.

A surface treatment device for applying a surface treatment to an inner surface of a hollow engine shaft includes a supply of a surface treatment agent and an elongated rod extending from a proximal end to a distal end. The rod has an inner passage extending from the proximal end to the distal end. The proximal end has an inlet fluidly coupled to the supply. The inner passage terminates at an outlet at the distal end. The rod is insertable inside the shaft. An input device is operable for controlling a delivery of a predetermined quantity of the surface treatment agent from the supply. An applicator disposed at the distal end of the rod adjacent the outlet is engageable with the inner surface of the shaft for applying, upon activation of the input device, the predetermined quantity of the surface treatment agent to the inner surface of the shaft.

The present invention consists in a nozzle for the efficient injection of viscous fluids into holes, cracks or groves through a mechanism preventing the draining outwardly of the volume to fill, which is obtained by incorporating to the injector's tip a screen with a central boring adjusted to the injector tip's surface, preferably of a semi-spherical form and of ferrous material, where said screen shows some freedom of movement levels with respect to the injector, thanks to screen's central boring being surrounded of magnets and having a semi-spherical profile that supplements the injector's tip.
