DESCRIPTION:
BRIEF SUMMARY
The invention relates to a rotor nozzle for a high-pressure cleaning device comprising a housing, a rotor rotatably mounted therein and set in rotation by a cleaning liquid, and a nozzle arranged downstream of the rotor with its outlet axis including a variable, acute angle with the axis of rotation of the rotor and rotated by the rotor about the axis of rotation thereof so that the jet of cleaning liquid issuing from it flows around the lateral area of a cone.
Such a rotor nozzle is known from German patent 36 23 368. With it, discharge of a point jet which flows around the lateral area of a cone is possible, and in the case of the known rotor nozzle, the angle of the lateral area of the cone can be widened as a function of the rotational speed.
The object of the invention is to further develop a generic rotor nozzle so that the operator can accurately adjust the angle of the lateral area of the cone around which the point jet flows independently of other operating parameters.
This object is accomplished in accordance with the invention with a rotor nozzle of the kind described at the beginning in that adjustable stops are arranged in the housing to limit to a greater or lesser extent the widening of the acute angle between the outlet axis of the nozzle and the axis of rotation of the rotor in accordance with the position of the limiting elements.
By adjustment of the stops it is readily possible to limit an inclined position of the nozzle and hence enlargement of the aperture angle of the lateral area of the cone. The operator can so displace these stops in the housing of the rotor nozzle that the stops then permit an inclination of the outlet axis of the nozzle which differs in extent in relation to the axis of rotation of the rotor.
In the case of a rotor nozzle with an elongated member which receives the nozzle and is supported with a spherical end in a socket which is open at the center and is held on the housing, while a follower which is connected to the rotor and is arranged at a radial spacing from the rotor axis engages the other end thereof, it is particularly advantageous for the stop to surround the elongated member concentrically with the axis of rotation of the rotor, to be adjustable in the direction of the axis of rotation of the rotor and to form a circumferential abutment edge resting on the outside of the elongated member.
Herein, provision may be made for the stop to be axially displaceably and with respect to the axis of rotation of the rotor rotationally fixedly mounted in the housing and to be screwed into a threaded bore arranged coaxially with the axis of rotation of the rotor in an adjustment sleeve which is axially immovably and with respect to the axis of rotation of the rotor freely rotatably mounted in the housing. Solely by turning this adjustment sleeve, the stop can be displaced in the axial direction inside the housing and the outlet angle of the point jet is thereby infinitely adjustable.
It is also advantageous for the follower to carry a radially extending groove in which the elongated member engages with a follower pin.
The adjustment sleeve can close off the housing at the end face thereof and carry the socket acting as bearing for the elongated member. In this way, the adjustment sleeve practically forms part of the housing, and the two housing parts are turned relative to each other about the longitudinal axis of the housing to bring about a change in the aperture angle of the jet.
In a particularly preferred embodiment, provision is made for a closable bypass pipe to issue from the interior of the housing located upstream of the nozzle into the region of the rotor nozzle located immediately downstream of the nozzle. Part of the cleaning liquid is thereby conducted past the nozzle and so the pressure of the point jet issuing from the nozzle can thereby be varied. This pressure variation is also further promoted by the quantity of liquid conducted past the nozzle in the bypass entering the point jet again in the region downstream of the nozzle and thereby breaking
