Patent number: 8919669Abstract: The present disclosure generally relates to fluid spraying devices and systems and more specifically, but not by limitation, to a fluid intake assembly configured to be used with a remote fluid source to supply fluid material from the remote fluid source to a fluid sprayer. In one example, a fluid intake assembly for a fluid sprayer is provided. The assembly includes an inlet tube providing at least a portion of a fluid path between a remote fluid source and the fluid sprayer. The assembly also includes a fluid flow control mechanism configured to allow a flow of fluid material in the fluid path in a first direction and restrict a flow of fluid material in the fluid path in a second, opposite direction. In one example, the fluid flow control mechanism comprises a valve mechanism.Type: GrantFiled: April 5, 2010Date of Patent: December 30, 2014Assignee: Wagner Spray Tech CorporationInventor: Jeffrey E.

Patent number: 8573511Abstract: The present disclosure generally relates to systems and devices for spraying fluid materials such as paints, stains, and the like, and more specifically, but not by limitation, to a dual voltage electromagnet motor for an airless fluid sprayer. In one example, a dual-voltage electric airless fluid sprayer is provided and includes a fluid reservoir and a pump configured to receive fluid from the fluid reservoir. An electric motor is operably coupled to the pump and includes a plurality of windings. The plurality of windings include a first winding portion having a first wire gauge and a first number of windings and a second winding portion having a second wire gauge and second number of windings. A power-module receiving portion is configured to receive a power module to couple one of the first or second winding portions to a source of electrical power.Type: GrantFiled: March 18, 2010Date of Patent: November 5, 2013Assignee: Wagner Spray Tech CorporationInventor: Jeffrey E.

Patent number: 8439586Abstract: A hand-held, battery powered liquid applicator having an on-board reservoir. An electric motor drives a piston in the reservoir via a pinion gear member and rack gear. A gear shifter may disengage the pinion gear member from the rack gear. A battery compartment may have a door has recess to enable a user to grasp a dry cell located farthest from the door. The rack gear may have modified profile teeth at the end of travel to allow the pinion gear member to slip when the piston is urged past the end of travel. The piston may have a length substantially equal to a characteristic length of the reservoir. Liquid may be drawn into the reservoir by powered or manual retraction of the piston and liquid may be delivered from the reservoir to an applicator head by powered or manual motion of the piston into the reservoir.Type: GrantFiled: September 26, 2008Date of Patent: May 14, 2013Assignee: Wagner Spray Tech CorporationInventors: Jeffrey E.
