Pressure Washer Adjustable Nozzle Assembly
First Claim
1. A pressure washer nozzle assembly comprising:
- a base that cooperates with a discharge end of a wand;
a nozzle associated with the discharge end of the wand and arranged to direct a fluid flow passed through the wand to atmosphere in a spray pattern, the nozzle defining a first fluid path aligned with a longitudinal axis of the nozzle;
a port that extends in a radial direction through the nozzle;
a collar engaged with the base and substantially surrounding the nozzle, the collar defining a discharge opening of the nozzle assembly and cooperating with the nozzle to define a second fluid path that is between the collar and the nozzle, the second fluid path being configured to selectively communicate a fluid flow from the port to the discharge opening of the nozzle assembly; and
wherein the collar cooperates with the base to be movable between a first axial position associated with suspending communication of fluid along the second fluid path to the discharge opening and a second axial position associated with fluidly connecting the second fluid path to the discharge opening of the collar.

Abstract
A nozzle assembly and method of forming an adjustable spray pattern nozzle assembly includes a mount body, a nozzle body, and a collar that movably cooperates with the mount body. The mount body is constructed to cooperate with a discharge end of a wand and such that the nozzle body can be captured between the mount body and the collar. The nozzle body defines an uninterruptible fluid flow path through the nozzle assembly. The nozzle assembly includes an interruptible fluid flow path that is defined by a positional relationship between the nozzle body and the collar. The collar movably cooperates with the mount body to allow the selective combination of flows associated with the uninterruptible and interruptible flow paths to manipulate the spray pattern generated by the nozzle assembly.

8. An adjustable spray nozzle assembly comprising:
-
a mount body that is securable to a discharge end of a wand; a nozzle body aligned with a longitudinal passage defined by the wand, a fluid passage defined by an interior surface of the nozzle body and aligned with the longitudinal passage defined by the wand; a collar engaged with the mount body, the collar being rotatable relative to the mount body, a discharge opening formed in the collar and aligned with the fluid passage defined by the interior surface of the nozzle body; and a seal face formed on a radially interior surface of the collar proximate the discharge opening, the seal face being axially movable relative to the nozzle body upon rotation of the collar between a contact engagement with the nozzle body and an offset position from the nozzle body such that only fluid associated with the fluid passage passes through the discharge opening when the seal face is in the contact engagement with the nozzle body and fluid associated with the fluid passage and fluid that passes between the collar and the nozzle body passes through the discharge opening of the collar when the seal face is at the offset position relative to the nozzle body. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of forming an adjustable nozzle assembly for generating multiple spray patterns, the method comprising:
-
providing a nozzle assembly mount configured to cooperate with a wand connectable to a pressure washer; providing a nozzle body that defines an uninterruptible fluid passage that extends in an axial direction through the nozzle body; providing a spray adjustment body that movably cooperates with the nozzle mount assembly, the spray adjustment body defining a spray outlet that is aligned with the uninterruptible fluid passage; and providing an adjustment interface between the spray adjustment body and the nozzle mount assembly, the adjustment interface being configured to accommodate rotational and axial translation of the spray adjustment body relative to the nozzle mount assembly to manipulate a size of a cross-section associated with an interruptible fluid passage defined by an interior surface of the spray adjustment body and an exterior surface of the nozzle body to allow selective combination of different fluid flows associated with the interruptible fluid passage with fluid flow attributable to the uninterruptible fluid passage. - View Dependent Claims (16, 17, 18, 19, 20)
