Abstract: A vehicle wash component at a vehicle wash location includes a processor for controlling an operational status of the vehicle wash component, an actuator communicatively coupled to the processor and configured to operate the vehicle wash component, and a power source electrically coupled to the processor and the actuator. The processor receives a signal from a car wash controller located at the vehicle wash location, the signal for commanding control of the vehicle wash component, and upon receipt of the signal, the processor interprets the signal, generates a separate signal, and transmits the generated signal to the actuator. The actuator receives the signal from the processor for controlling the operational status of the vehicle wash component based thereon. The power source provides power to the actuator for operating the vehicle wash component based on the operational status of the vehicle wash component.

Abstract: A pneumatic excavator is configured to be pneumatically actuated using a safety mechanism, and includes a primary actuator; a secondary actuator fluidly coupled to the primary actuator; a flow valve fluidly coupled to the primary actuator; a shuttle valve fluidly coupled to the primary actuator, the secondary actuator and the flow valve; and a barrel coupled to an egress of the flow valve, the barrel defining an outlet of the pneumatic excavator. Actuating the primary and secondary actuators causes compressed air to be transmitted from the secondary actuator to the primary actuator and then to the flow valve to open the flow valve such that the compressed air exits through the outlet. Actuating one actuator and not the other causes the compressed air to be transmitted to the exit port of the shuttle valve and then to the flow valve to close the flow valve and prevent air flow therethrough.

Abstract: A pneumatic excavator includes: a barrel with an ingress configured to be fluidly connected to a supply of compressed air and an egress; an actuator; a releasable coupling to lock the actuator to the barrel in a plurality positions; and a flow valve fixedly arranged to the barrel, the flow valve in a communicative coupling with the actuator by an actuation conduit. The actuation conduit is flexible and slaved by an adjustment movement of the releasable coupling and actuator along the barrel to thereby maintain the communicative coupling therebetween. When the actuator is actuated, the actuation conduit sends causes the flow valve to open and the compressed air passes through the flow valve and exits the pneumatic excavator, and when the actuator is released, the actuation conduit sends a signal to the flow valve to close to prevent the compressed air from passing through the flow valve.

A rotor member having at least one lobe engaged with one or more cavities of a stator surface for defining an oscillatory movement of the rotor member in response to a motive fluid along the rotor member and stator surface. The nozzle assembly directing the motive fluid along one or more tapered surfaces, such as complementary tapered surfaces of the rotor and stator surface. The rotor member is operatively coupled with the spray member for oscillatory movement therewith. The spray member adapted to receive the motive fluid and emit the fluid as a spray from the nozzle assembly. The spray having an oscillatory pattern that matches the oscillatory movement of the rotor.

Abstract: A pneumatic excavator for delivering pulsed compressed air includes an actuator; a controller valve; a flow valve; a barrel defining an outlet of the excavator; and a pulse control line extending between the controller valve and a port downstream from an egress of the flow valve. As compressed air flows through the egress of the flow valve, the pulse control line is pressurized and shifts the controller valve to an actuated position, causing the compressed air from the actuator to close the flow valve, thus preventing the air flow from passing through a primary flow passage and through the outlet. The pulse control line being no longer pressurized by the air flow, then causes the controller valve to move to an unactuated position to cause compressed air from the actuator open the flow valve and permit the air flow through the outlet and again pressurize the pulse control line.

Abstract: A foam generating device includes a housing defining an agitation chamber and a conditioning chamber. A cartridge assembly arranged within the agitation chamber defines an agitation flow path of the solution to increase a quantity of a gas in the solution. A conditioning assembly arranged within the conditioning chamber defines a tortuous flow path for the solution including a plurality of cylindrical discs configured to sequentially receive the solution. Each of the discs defines a plurality of radial ribs on a first side and on a second side opposite the first side, the first and second sides separated by a floor, and a disc passage defined in the floor. The conditioning assembly is adjustable in order to selectively define the tortuous flow path with a first quantity of radial ribs and second quantity of radial ribs in order to alter the aeration of the solution along the tortuous path.

Abstract: A dilution device may include a first component and a second component. The first component may define a groove including an inlet portion and an outlet portion. The second component may define an inlet in fluid communication with the inlet portion of the first component and an outlet in fluid communication with the outlet portion of the first component. Relative rotation between the first component and the second component may cause relative movement between the outlet and the outlet portion that changes the effective length of the groove fluidly coupling the inlet and the outlet of the second component. The cross-sectional area of the groove may vary along a length of the groove to provide different flow characteristics depending on the effective length of the groove.
