Abstract: Device for applying a product, including a frame in which a product conduit is provided, the frame defining a longitudinal bore, the device including a needle mounted in the longitudinal bore, the device including a product application valve formed by a nozzle provided on the frame and a shutter provided at an end of the needle in the product conduit. The needle is configured to be moved along a longitudinal axis between a closed position and an open position of the dispensing valve. The device includes a stop fixed in relation to the needle, and a stop fixed in relation to the frame, configured to limit the return of the needle towards its closed position to an intermediate position between the closed and the open position, by interaction with the stop fixed in relation to the needle, and the stop fixed in relation to the frame has an adjustable position.

Abstract: The present invention concerns an air motor comprising a piston and a housing, the piston being received in the housing and dividing the housing into two primary chambers of variable volume. Said motor comprises a first direct supply valve for supplying a first primary chamber of the two primary chambers and a second direct supply valve for supplying the other primary chamber, said two valves each being movable relative to at least one respective seat. The first valve and the second valve are mounted on a same stem movable relative to the housing in a direction parallel to the direction of movement of the piston, and the stem is configured to be moved between a first position and a second position by moving means activated by the piston.
