Abstract: A paint sprayer includes an end bell, a motor connected to the end bell, a pump drive connected to the end bell, a pair of protrusions attached to an extending from the end bell such that each protrusion is cantilevered from the end bell, and a pump assembly comprising a pair of mounting holes and containing a piston. The pair of mounting holes is adapted to receive and slide onto the pair of protrusions to mount the pump assembly on the end bell as well as slide off of the pair of protrusions to remove the pump assembly from the end bell. The pump drive is configured to covert rotational motion output by the motor to reciprocal motion. The pump assembly is configured to pump paint when reciprocated by the pump drive while mounted on the end bell.

Abstract: A high-pressure low-volume spray system includes a hose disposed between a compressor and a spray gun. The hose acts as an accumulator when the spray gun is deactivated. A check valve is disposed in a fitting connecting the hose to the compressor. The check valve includes a spring that applies a nonlinear force to a downstream end of a valve member, such that the valve member tips open in response to the pressure differential, providing a variable flowpath opening through the check valve.

Abstract: A rotational output assembly is configured to provide power to a drive assembly to cause pumping by a pump. The rotational output assembly includes an electric motor and a pinion drive projecting axially from the motor. The pinion drive interfaces with bearings supported on a pump frame. The pinion drive includes a gear teeth section between portions interfacing with the bearings supported on the pump frame. The gear teeth section interfaces with a drive gear of the drive assembly to cause rotation of the drive gear.
