An injector apparatus and methods for use, where the injector apparatus comprises: (a) hydraulic stage having first and second ends and including a housing defining a cavity, a primary plunger disposed in the cavity and a secondary plunger, (b) a pressurization system coupled to the hydraulic stage's first end, where the primary plunger is in fluid communication with the pressurization system and is in mechanical communication with the secondary plunger, (c) a reservoir bore defined in the hydraulic stage housing and configured to receive the primary plunger's second end, where the secondary plunger is disposed within the reservoir bore and (d) a nozzle assembly including a housing, a gas tube and a nozzle capillary, where the nozzle capillary is partially disposed in and is substantially coaxial with the gas tube, where the nozzle capillary's first end is in fluid communication with the reservoir bore's second end.

The invention relates to a nozzle head for a spray device, comprising a central material nozzle, an air ring nozzle surrounding said material nozzle, and preferably at least two laterally projecting horns, into each of which at least one horn air nozzle is incorporated, and optionally comprising a material-conducting needle, characterized in that at least one nozzle (3, 3a, 3b, 5, 5a, 12, 12a, 12b, 15, 16, 17, 17a, 17b, 17c, 18, 18a, 18b1, 18b2, 18b3, 300a, 300b), preferably at least one horn air nozzle (15, 16, 17, 17a, 17b, 18, 18a, 18b1, 18b2, 18b3, 300a), has a non-cylindrical shape.

A pneumatic cleaning gun according to the present invention comprises a gun housing with a compressed air connection, a liquid nozzle with a nozzle cover, and an air intake tube which leads into the covered flow channel and can also be connected to a suction device via a suction hose in order to suction dirt particles through the flow channel. The cleaning gun is configured such that the air intake tube is not rigidly but pivotably mounted on the cleaning gun. The air intake tube can therefore be mounted in a plurality of different positions of use such that the user can find the most comfortable or convenient position of use and the air intake tube can be correspondingly adjusted.

A spray gun nozzle is provided, including: a hood located outside a central nozzle and connected to a spray gun; an annular snout sleeved on the hood and connected to the hood, wherein the annular spout includes: a first pipe body; a second pipe body sleeved with the first pipe body; an annular bottom surface connected with an end of the first pipe body and an end of the second pipe body, wherein the first pipe body, the second pipe body and the annular bottom surface form an annular cavity; and an annular spout air inlet provided on the annular bottom surface and communicated with the annular cavity; and an annular spout air inlet pipe connected with the annular spout air inlet.

In a cleaning method for removing adhesive residues from surfaces, in particular after separating an adhesive connection between adhesively joined partners, liquid carbon dioxide from a reservoir enters a jet, apparatus and is guided there through a first dosing unit into an expansion chamber wherein a cold-resistant liquid is then supplied to a mixture created in the expansion chamber from gaseous carbon dioxide and carbon dioxide particles and wherein the mixture, to which the cold-resistant liquid has been added, exits the jet apparatus via an outlet opening thereof. Furthermore, a jet apparatus removes adhesive residues from surfaces.
