L'invention concerne les compresseurs et les aérographes. Elle se rapporte à un appareil de pulvérisation comprenant un compresseur portatif 10 alimenté par une batterie d'accumulateurs et dans lequel un petit moteur provoque la compression alternative de soufflets qui transmettent un débit pratiquement régulier d'air comprimé à un aérographe 20 dans lequel un organe de commande 20 limite la course d'une détente 70 de manière que le débit obtenu soit précis et reproductible. Application aux aérographes et à leurs compresseurs. A small and lightweight compressor has a motor which generates rotational drive which is converted into reciprocating movement to actuate an air compressing mechanism to thereby discharge compressed air. Three or more air compressing members are successively operated with a phase difference therebetween to thereby continuously discharge a smooth current of compressed air out of a discharge hole. The compressor can be part of a spray apparatus with an air brush in which a movable needle valve is inserted in a liquid path. The needle is moved by operation of a rod 70. Compressed air from the compressor is communicated with the air path to thereby spray the liquid. The air brush has a control surface which is the upper surface of a base portion of the rod, which is pivotable with respect to the body. A sliding member is axially movably disposed so that when the rod is actuated (manually usually), the amount of movement of the rod (i.e. its range of movement) can be adjusted by making the lower end of the sliding member abut against the control surface.
