Abstract
A paint sprayer includes a housing and a syringe assembly coupled to the housing with a reservoir and a plunger positioned within the reservoir. The reservoir is configured to store fluid. The paint sprayer also includes a spray assembly in fluid communication with the syringe assembly. The spray assembly includes a spray nozzle and a spray tip. The spray tip is configured to expel fluid. The paint sprayer further includes a motor pump assembly disposed in the housing and an actuator operable to energize the motor pump assembly to draw fluid from the reservoir and expel it from the spray tip.
Claims20
A paint sprayer comprising:
- a housing;
- a syringe assembly coupled to the housing, the syringe assembly including a reservoir and a plunger positioned within the reservoir, the reservoir configured to store fluid;
- a spray assembly in fluid communication with the syringe assembly, the spray assembly including a spray nozzle and a spray tip, the spray tip configured to expel fluid;
- a motor pump assembly disposed in the housing;
- an actuator operable to energize the motor pump assembly to draw fluid from the reservoir and expel it from the spray tip.
A syringe assembly comprising:
- a reservoir defining a first end, a second end opposite the first end, and a central axis extending centrally through the tube between the first and second ends;
- an end cap coupled to the first end of the reservoir, the end cap defining a central opening;
- a valve positioned in the central opening;
- and
- a plunger disposed within the reservoir, the plunger operable to move between a first forward position adjacent the first end of the reservoir and a second rearward position adjacent the second end of the reservoir;
- wherein the syringe assembly is configured to be coupled to a paint sprayer in a first position, in which, the paint sprayer is operable to draw fluid from the reservoir, and a second position, in which, the plunger is operable to move from the forward position to the rearward position to draw fluid into the reservoir.
A fill assembly for a paint sprayer comprising:
- a straw assembly including a straw defining an opening, the straw including a first end and a second end opposite the first end;
- and
- a syringe assembly removably coupled to the second end of the straw, the syringe assembly including
- a reservoir configured to retain fluid, the reservoir including a first end, a second end opposite the first end, and a central axis extending centrally through the reservoir between the first and second ends, and
- a plunger positioned within the reservoir, the plunger operable to move between a first forward position adjacent the first end of the reservoir and a second rearward position adjacent the second end of the reservoir.
