Abstract: The invention concerns a connector piece with a screw collar ring for the hose coupling of high-pressure cleaning equipment, the hose coupling having a sleeve with a conical sealing surface and, adjacent to it, a cylindrical sealing surface, plus an external thread for the collar ring of the connector piece, while the connector piece has a cylindrical nipple with a ring seal designed to make a tight seal with the cylindrical sealing surface of the coupling sleeve plus a convex shoulder designed to make a tight seal with the conical sealing surface of the sleeve, the collar ring being fitted so that it can turn freely on the connector piece and so that essentially it cannot move in the longitudinal direction. In order to improve the mechanical protection offered to the coupling components against damage, the invention proposes that the collar ring projects longitudinally over the free end of the nipple and that the ratio of the length of the nipple to its outer diameter is between 0.4 and 0.3.

Abstract: The invention concerns a high-pressure cleaning apparatus with a high-pressure pump for a cleaning fluid and with a heat exchanger which comprises a fossil fuel burner (9) and a helical pipe (13) through which the cleaning fluid flows and into whose interior (16) the burner (9) directs the hot combustion gases. According to the invention, in order to optimize the transfer of heat, the height of the cylinder formed by the helical pipe (13) is between three and seven times the internal diameter of this cylinder.

Abstract: A high-pressure cleaning device comprises a rotor (10) rotatably mounted in a housing and set in rotation by a cleaning liquid, and a nozzle (33) downstream of the rotor (10) whose outlet axis makes a variable acute angle with the axis of rotation of the rotor (10). The nozzle (33) is rotated by the rotor (10) about the axis of rotation of the latter so that the jet of cleaning liquid issuing from the nozzle flows around a conical shell. To enable the outlet angle of the point jet to be set without the need to modify other parameters, adjustable limit stops (46) are arranged in the housing (1) and limit to a greater or lesser extent the widening of the acute angle between the outlet axis of the nozzle (33) and the axis of rotation of the rotor (10) in function of the position of the limiting elements.
