FIELD: engineering elements.
SUBSTANCE: invention relates to a high-pressure injector. The technical result is achieved by a high-pressure injector provided with a filter, a supply channel, flow-conducting surfaces, a jet rectifier, a compression channel, a sealing ring, a nozzle with an outlet, and a body of the nozzle. The filter, the supply channel, the jet rectifier, and the compression channel are therein made in one manufacturing cycle as a single part in the form of a stabiliser filter, the shape of the outer surface whereof constitutes a cylinder transitioning into a uniformly tapering cone. The filter is therein made in the form of rounded inlet slots on the cylindrical surface of the stabiliser filter, and the inner surface of the jet rectifier is made in the shape of a cone tapering towards the outlet, and the flow compression channel is made in the form of a branch pipe smoothly tapering from the maximum diameter on the side of the jet rectifier to the diameter of the input section of the nozzle.
EFFECT: increase in the uniformity of the flow and parallelism of the flow of the longitudinal axis, reduction in pressure losses and, therefore, increase in the impact force.
