Abstract: A piston rod assembly includes a piston rod having a first end configured to contact fluid, a packing retainer through which the piston rod extends, and one or more packing rings. The packing retainer includes one or more leakage ports forming passageways between an inner surface and an outer surface of the packing retainer. The one or more packing rings surround the piston rod, are adjacent the inner surface of the packing retainer, and are positioned between the one or more leakage ports and a bottom end of the packing retainer. The one or more leakage ports are positioned so that fluid that leaks past the one or more packing rings will flow through the one or more leakage ports.

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 fluid spraying system includes a displacement pump configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring that includes threading is configured to rotate about a cylinder of the pump and shift axially along the cylinder and engage with a bottom side of the drive housing to secure the displacement pump to the drive housing.

Abstract: A pump rod has a head extending from a neck, and the head is received within a drive slot of a drive link. The head includes a projection, and has an area smaller than an area of the head. The projection contacts an inner surface of the drive slot. The drive link may include a projection aligned with a centerline of the drive link. The drive link projection contacts a head of the pump rod. The projections provide a reduced contact area between the pump rod and the drive link, thereby reducing any side-loading on the pump rod and increasing a lifespan of the wear parts.

Abstract: A motor assembly includes a shaft, an electric motor operatively connected to the shaft to drive the shaft in a first rotational direction, a clutch assembly connected to the shaft, and a fan connected to the clutch assembly and configured to supply the electric motor with cooling air. The clutch assembly drives the fan when the electric motor drives the shaft and allows the fan to freewheel in the first rotational direction when the electric motor is not driving the shaft. A method of operating a fan cooled electric motor includes energizing the electric motor to drive a shaft in a first rotational direction using the electric motor and de-energizing the electric motor so that it no longer drives the shaft, allowing the fan to freewheel in the first rotational direction.

Abstract: A piston rod and piston head are the driven components within a pump. An upstream end of the piston rod is attached within an aperture of the piston head. At least one flute extends between the upstream end of the piston rod and the aperture, and the at least one flute is configured to provide a flowpath for a fluid, such as paint, to flow downstream of the piston head and piston rod. The flutes facilitate a smooth downstream flow of the fluid, thereby reducing hydraulic resistance and reducing wear caused by the fluid.

Abstract: A piston is the driven component within a pump. The piston is driven along a longitudinal axis to pump a fluid through the pump. The fluid flows through the piston between an upstream end of the pump and a downstream end of the pump. The piston outputs the fluid into the downstream end of the pump at a vector offset from the longitudinal axis, thereby inducing rotation of the piston throughout the pumping process. Rotating the piston encourages even wear on various components within the pump, such as sealing rings surrounding the piston, thereby increasing the lifespan of the components and increasing the efficiency of the pump.
