The water gun comprises a cylinder, a piston fitted in a cavity of the cylinder, a pump rod connected to the piston, a handle disposed on the pump rod, and a water duct mounted on and communicating with the cylinder. The nozzle is mounted on the water duct, rear and front ends of the nozzle are disposed with a water inlet and a water outlet respectively, and the water inlet communicates with the water duct. The adjustment sleeve is sleeved on the nozzle, an inner side wall of the adjustment sleeve makes sealing contact with an outer side wall of the nozzle, the adjustment sleeve is disposed with a sealing plate having a water jet hole located right in front of the water outlet.

A pump draws fluid from a reservoir and drives the fluid downstream to a spray tip where the fluid is applied to a surface. A piston is driven in a reciprocating manner to pump the fluid. A check valve is disposed downstream of the piston to regulate a flow of the fluid downstream from the piston. The pump is initially dry and is primed with fluid prior to operation. To facilitate priming, the piston is dimensioned to impact the ball and unseat a valve member of the check valve during a priming stroke, thereby ejecting any air from the pump through the check valve. With the air ejected from the pump, a vacuum is formed during a suction stroke of the piston, which draws fluid downstream from the reservoir to prime the pump.

An example of a device (100) may include a valve body (108). The device (100) may include a printing substance transfer aperture (122) through the valve body (108). The device (100) may include a hood (138), fixed to the valve body (108), encompassing the printing substance transfer aperture (122) within a cavity between an external face (137) of the valve body (108) and the hood (138). The device (100) may include a printing substance dispensing nozzle (110) movable between a first position with an orifice (126) of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second position with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer aperture (122). The device (100) may include a dispensing-side gasket material (132) slide-able through the printing substance transfer aperture (122) when moving the printing substance dispensing nozzle (110) between the first position and the second position.

A spray gun alignment system precisely aligns a spray gun of a container spray machine for precision application of container coatings. The spray gun alignment system generates a spray gun alignment jig including a container holder adapter and a spray gun adapter. The container holder adapter is inserted into a container holder of the spray machine, and the spray gun adapter is fastened to the spray gun. The spray gun alignment jig is configured to position the spray gun in proper alignment with respect to the container holder.

A liquid material discharge device includes: a plunger including a piston formed at a rear end a piston chamber in which the piston is disposed and to which pressurized gas is supplied; a pressure supply device that supplies, to the piston chamber, air pressurized in excess of the urging force of the elastic body, or that purges pressurized air out of the piston chamber, the liquid material discharge device discharging the liquid material from the discharge port by causing the plunger to move forward and applying an inertial force to the liquid material; a booster circuit that communicates the pressure supply device and an air source with each other, and the booster circuit includes a first and a second booster system including a booster valve and a pressure reducing valve, and a merging section in which the first booster system and the second booster system merge together.

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston. The piston is configured to pressurize at least one pumping chamber. A motor is connected to the reciprocating piston fluid pump to actuate the piston. A spray tip connected to an outlet of the at least one pumping chamber.

The device for dispensing gel or liquid contained in a container comprising a reservoir provided with a pump set in motion relative to the reservoir, comprises a body. The body comprises in the lower part, an actuating pedal and at the top, above a support for a reservoir of said container, a space for receiving any gel or liquid container having dimensions less than predetermined maximum dimensions. The body also comprises a piston for transferring the vertical movement of the pedal to the reservoir support, setting the reservoir in upward movement under the action of the pedal, and a stop for retaining the pump of the container provided with a pouring spout. The pump causes a part of the gel or liquid contained in the reservoir to be expelled when the reservoir is moved by the action of the pedal.

The present invention for rights for a system configured for use with an existing motor vehicle windshield washer system whereby a portion of solution is directed to a headlamp washing outlet.

An indoor gardening appliance includes a grow module that is rotatably mounted within a grow chamber and that defines pod apertures for receiving a plurality of plant pods. A hydration system includes a nozzle assembly for selectively discharging a nutrient mixture from a mixing tank to hydrate plants within the grow chamber. The nozzle assembly includes a hydraulic cylinder including a piston positioned within a cylindrical chamber. An actuator moves the piston to a fully retracted position to draw in enough nutrient mixture for a single hydration cycle and then moves to a fully extended position to discharge the nutrient mixture. An intake check valve prevents undesirable backflow into the mixing tank and a discharge check valve prevents undesirable backflow into the cylindrical chamber.

An applicator system for applying a material to a substrate is disclosed, the applicator system having a nozzle assembly (28) that includes a nozzle having a nozzle head (108). The nozzle assembly (28) also includes a baffle plate (101) including a cutout (144) that extends through the baffle plate (101), where the baffle plate (101) is received by the nozzle head (108) such that the nozzle head (108) and the baffle plate (101) define a cavity. The nozzle assembly (28) further includes a cover plate (102) attached to the nozzle head (108) such that the cover plate (102) secures the baffle plate (101) within the nozzle head (128), where an outlet passage is defined between the baffle plate (101) and the cover plate (102), the outlet passage being fluidly connected to the cavity through the cutout (144) of the baffle plate (101).
