An apparatus for use in drywall plastering, and more specifically for applying a pumpable finishing compound to a surface, is disclosed. The apparatus comprises a receptacle for storing the pumpable compound, an applicator for applying the compound to a surface or feature to which the compound is to be applied, a pump for pumping the compound from the receptacle to the applicator for application to the surface or feature, an electric motor which drives the pump, a battery that powers the electric motor, and a conduit through which the compound is pumped from the receptacle to the applicator, and the receptacle, pump, motor and battery of the apparatus may be able to be worn by a user, or carried on a part of the user’s body, while the apparatus is in use for applying the compound to the surface or feature. The apparatus is self-contained and self-powered, and it can consequently operate in an “untethered” manner in the sense that it does not require any power cables extending from the apparatus to a remote power outlet or generator, and there is no need for any hoses or the like to deliver finishing compound, or compressed air, or anything like that, to the apparatus while it is in use.

A spray system for spraying a fluid, the spray system including a tank for holding the fluid; and a sprayer including a fluid conductor, a fluid mover, at least one first nozzle and a second nozzle, the fluid conductor including an inner diameter, a first end configured to be connected to the tank, a second end configured to be selectively connected to one of the at least one first nozzle and a second nozzle, wherein the second nozzle including a through opening at least about the same size as the inner diameter, wherein the fluid mover is configured to draw the fluid from the tank through one of the at least one first nozzle to create a spray of the fluid and the second nozzle to return at least a portion of the fluid to a storage tank.

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.

A hard surface cleaning and conditioning assembly is provided that includes a pole having a lower section and an upper section; an adjusting device securing the upper and lower sections to one another in a telescoping manner; a tool depending from the lower section; a conditioning agent dispensing device depending from the lower section; a trigger depending from the upper section; and a telescoping trigger assembly operatively connecting the dispensing device to the trigger.

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 nozzle is disclosed that includes a nozzle body having a first portion with a cylindrical configuration and a second portion including a dome-shaped end wall. The first and second portions of the nozzle body define an internal fluid passage having a downstream end defined by the dome-shaped end wall. A flow control element is arranged at an inlet end of the internal fluid passage. The flow control element includes a pre-orifice through which fluid can enter the internal fluid passage of the nozzle body. First and second discharge orifices are provided in the dome-shaped end wall with each of the first and second discharge orifices being arranged on a respective one of opposing sides of an apex of the dome-shaped end wall. The first and second discharge orifices are configured to produce a fan-shaped fluid discharge pattern with each discharge orifice having an elongated slit-like configuration.

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.

A backpack material dispenser that includes a pumpless pressure tank for storing and discharging a material under pressure contained in the pressure tank and a hose and a shut off valve connected to an output opening of the pressure tank for allowing flow of the material from the pressure tank under pressure and through a nozzle communicating with a discharge end of the hose. A discharge valve communicates with the nozzle proximate the hose for allowing controlled discharge of the material from the nozzle. A backpack assembly mounts the pressure tank for being carried by a user. A charging tank contains a gas under pressure to charge the pressure tank to a predetermined pressure, and a releasable connector of the charging tank attaches to a complementary connector of the pressure tank for charging the pressure tank with the gas under pressure to the suitable pressure tank pressure.

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 disposed within a cylinder. The piston is configured to pressurize at least one pumping chamber. A motor is coupled to the housing and connected to the reciprocating piston fluid pump to actuate the piston. A wobble assembly connects the motor to the piston of the reciprocating piston fluid pump. A spray tip connected to an outlet of the at least one pumping chamber.
