An effective implementation is shown for a height adjustment system for one or more spray guns used in a line striper.

Disclosed herein is a tool for holding a spray painting instrument, such as a painting gun for painting an internal surface of a pipe. In particular, the inventive tool is ideal for painting the interior of curves and angles in a pipe and is capable of moving through and uniformly painting up to 90 degree angles of pipes or hollow tubes. The tool has a hollow central tube for carrying a spray-painting gun and at least two projections extending outwardly from an outer surface of the hollow tube. A retracting arm assembly is provided on each projection. Each retracting arm assembly includes first and second retracting arms and a corresponding force exertion mechanism. In operation, when the tool is inserted inside the pipe, each retracting arm touches the internal surface of the pipe due to an outward force exerted thereon. The tool is movable inside the pipe and adjusts automatically to different pipe diameters. The tool can be used manually or in an automated fashion to push and pull the paint gun and paint the interior of a pipe.

According to an implementation, a pressure washer system may include a pump and an engine drivingly coupled with the pump. A pressure washer controller may be associated with one or more of the pump and the engine. A battery may be communicatively coupleable with the pressure washer controller for one or more of receiving data from the pressure washer controller and transmitting data to the pressure washer controller. The battery may include a memory module for storing one or more of data received from the pressure washer controller and data to be transmitted to the pressure washer controller.

A sprayer accessory holder provides a place to put multiple tip housings and multiple spray tip nozzles. The sprayer accessory holder can be a separate piece that is attached to an airless sprayer, can be part of a replacement part for an airless sprayer, or can be part of a new part on an airless sprayer. The sprayer accessory holder preferably includes a plurality of retaining members, one or more of which is dimensioned to receive a tip housing and one or more of which is dimensioned to receive a spray tip nozzle. Each retaining member can have external dimensions to receive a tip housing and a substantially hollow interior with an opening dimensioned to receive a spray tip nozzle, allowing a user to use each retaining member for a tip housing or a spray tip nozzle at the user's discretion.

A fluid applicator configured to receive a pressurized fluid includes a pressure vessel configured to receive the pressurized fluid from a fluid delivery line. The pressure vessel includes a valve chamber configured to receive a valve assembly, a filter chamber configured to receive a filter assembly, and a fluid delivery line configured to be coupled to the fluid delivery line. The fluid applicator further including a tip assembly coupled to the pressure vessel and configured to atomize the pressurized fluid.

Methods and systems for controlling pressure washer devices are provided. Pressure washers comprising at least one control unit and the ability to regulate functions of at least an engine of a pressure washer are disclosed. A control unit receives inputs from a user or various sensors provided in communication with the control unit, and is further capable of outputting a signal based on the inputs, the output signal operative to maintain or control the operating functions of an engine, pump, or motor.

A spreader for spreading a material including at least one pair of rotating discs having a plurality of generally radially oriented blades attached thereon for disbursing the material in a pre-selected pattern. The discs are rotatably positioned below an end of a funnel unit to receive material passing through the funnel units. The material, as it passes through the funnel units, is directed to a predetermined impact region on each of the rotating discs by a corresponding pair of deflecting vanes integrally fit and movably attached within each funnel of the pair of funnel units. Each deflecting vane is selectably movable by a corresponding actuator from a first position to a second position while the spreader is operating.

A sprayer equipment includes a support frame, a pump, a pressure regulator, a concentrate tank, an injector, a spray nozzle, and a controller. The support frame has a plurality of wheels. The pump is coupled to the support frame and includes a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure. The pressure regulator is configured to control the pressure of the water. The concentrate tank is supported by the support frame and configured to store a concentrate fluid. The injector is fluidly coupled to the concentrate tank and configured to inject the concentrate fluid into the water. The spray nozzle is fluidly coupled to the pump outlet and the injector. The controller is coupled to the injector and is configured to control operation of the injector.
