ABSTRACT:
A pressure-washer nozzle has an inner sleeve generally centered on and extending along an axis and having a rear end formed as a high-pressure liquid inlet, an outer sleeve coaxial with and rotatable but axially nondisplaceable on the inner sleeve, and a rear nozzle body in the inner sleeve formed with a small-diameter axially throughgoing central rear passage opening at a front face of the rear nozzle body. The rear nozzle body further forms with the outer sleeve an array of outer rear passages. A front nozzle body in the inner sleeve forward of the rear nozzle body has a large-diameter axially throughgoing front passage coaxial with the rear passage. The front body is formed with a rear face engageable flatly with the front face of the rear nozzle body and this front body is movable axially in the inner sleeve between a front position with the faces spaced axially apart and flow possible through the inner and outer passages to the front passage and a rear position with the faces engaging each other and flow through the outer passages blocked. The outer sleeve is coupled with the front nozzle body to displace the front nozzle body axially relative to the rear nozzle body between its positions on rotation of the outer sleeve relative to the inner sleeve. A diverter can be mounted between the nozzle bodies and a rear guide to provide selective rotary action if desired.
