FIELD: mechanics.
SUBSTANCE: device for injection of a liquid requires at least one pneumatic pump, hydraulically connected with at least one injection head having orifices for atomisers. The injection composition comes from the pneumatic pump in the head mainly through the filter arranged in the said injection head using no threaded joints. For additional reduction of the danger of pollution, the liquid fed into the injection head, does not get into contact with whatever threaded joints arranged in the head or atomisers. There is an air pressure controller to ensure a regular feed of the injection composition jet at a required pressure to the object of injection through each injection head, and to reduce irregularities in liquid feed by air-operated pump. Mobile sensitive components are placed in a tight casing that excludes their direct contact with a damp working medium.
EFFECT: simpler device cleaning.
