A ground sprayer includes a front portion and a rear portion. A marking fluid is stored in a fluid reservoir removably mounted in the front portion. A pump disposed in the front portion draws the marking fluid from the fluid reservoir through a manifold, and the pump drives the marking fluid out of a nozzle. An actuator is disposed in the rear portion and can activate the pump based on a command from the user. The rear portion includes a handle such that the user can fully support and operate the ground sprayer with a single hand.

A device that can hold at least two cans of spray paint or chalk, thus enabling marking with different colors using a single device. The device comprises a staff, a can holster, a grip, a trigger and a selector. The selector comprises a selector rod moveable in or alongside the staff. At one end of the selector rod is a selector knob and at the other is an engagement mechanism that engages the spray valve of each can, one can at a time. The engagement mechanism comprises a cam and a rocker arm with two opposing fingers, one to engage each spray can when selected. Optionally one or more flag holders may be attached to the staff for holding marker flags.

A swivel connector for a spray gun includes a first portion, the first portion including a first interior passage that extends entirely through the first portion along a longitudinal axis and a second a second interior passage that extends along a first axis perpendicular to the longitudinal axis. The swivel connector also includes a second portion coupled to the first portion, the second portion including a third interior passage that extends entirely through the second portion along the longitudinal axis, and a fourth interior passage that extends along a second axis perpendicular to the longitudinal axis. The swivel connector also includes a connector pin coupled to both the first portion and the second portion, wherein the connector pin includes a fifth interior passage that extends along the longitudinal axis.

The invention relates to a dispenser comprising: a pump (P) comprising a pump body (P1) defining an inlet (P3), a cap (1) rigidly connected to two reservoirs, the cap (1) forming a reception cavity (10), the cap (1) defining at least two connecting ducts (16, 151) each connecting one reservoir respectively, characterised in that the dispenser further comprises an endpiece (2) rigidly connected to the pump body (P1), the endpiece (2) defining an interior space (20) which communicates with the inlet (P3) and at least two through-holes (241, 261) which connect the outside of the endpiece (2) with the interior space (20) thereof, the endpiece (2) being rotatably mounted in the reception cavity (10) in order to establish fluid paths between the connecting ducts (16, 151) of the cap (1) and the through-holes (241, 261) of the endpiece (2).

A flow rate control valve has a waterproof function of a driving motor. The flow rate control valve is for transferring a fluid pumped by a water supply pump to a nozzle unit and a nozzle cleaning unit for cleaning the nozzle unit. The flow rate control valve includes at least one housing in which the fluid pumped by the water supply pump is accommodated, and at least one driving motor configured to change a communication area of each of the at least one housing, the nozzle unit, and the nozzle cleaning unit by rotation. At least one sealing adapter is formed between the at least one housing and the at least one driving motor so as to prevent the fluid from flowing into the at least one driving motor.

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.

The sprayer includes a housing defining a chamber, and a cylinder within the chamber. The cylinder defines more than one discharge tube positioned in a longitudinal direction within the housing, the cylinder being selectively rotatable within the chamber. More than one suction tube extends from a lower portion of the housing. The more than one suction tube is in selective fluid communication with the more than one discharge tube of the cylinder, as the cylinder is rotated within the chamber.

A liquid container includes a casing, at least two inner bottles for containing liquids, at least one pumping unit, a turnable selecting mechanism, and a top cover. The inner bottles are received in the casing and covered by the top cover. The selecting mechanism is operated to select one of the inner bottles to be pumped, and then the pumping unit is operated to pump out the liquid contained in the selected inner bottle through an outlet located on the top cover. Not only weight and volume for carrying these liquids can be decreased, but also convenience for accessing these liquids is improved by using the aforesaid liquid container.

Disclosed herein are devices, systems, and methods for dispensing fluids. One general aspect includes a multi-chamber fluid dispenser. The multi-chamber fluid dispenser includes a container and a cap. The container has a plurality of chambers formed therein. Each of the chambers in the plurality of chambers is configured to store fluid therein. The cap is for covering the container. The cap includes a distributor through which fluid stored in any one of the chambers in the plurality of chambers is allowed to be expelled from the container Each of the chambers in the plurality of chambers is configured to be in fluid communication with the dispenser such that fluid is dispensable from the container in at least one of the following manners individually as an individual fluid and together as a mixed fluid.

A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes a pump mechanism that includes a pivotable trigger and a first plunger cavity that is disposed along the first flow path for receiving the first fluid and a second plunger cavity for receiving the second fluid. The pump mechanism also includes a first plunger that is disposed and movable within the first plunger cavity and a second plunger that is disposed and movable within the second plunger cavity. A selectable actuator is movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a nozzle by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the nozzle by causing the second fluid to flow along a second flow path.
