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 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 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 displacement pump includes a pump rod having a load concentrating feature extending from the head of the pump rod. The head of the pump rod is received within a slot of a drive link, and the drive link is configured to contact the load concentrating feature. Having the drive link contact the smaller diameter load concentrating feature reduces the misalignment between the driving force and the center of the pump rod and thereby reduces side-loading experienced by the pump rod. The displacement pump is configured to be used in a fluid dispensing system.

Abstract: An electro-hydraulic actuation system for a sprayer comprises a hydraulic system, a hydraulic actuator, an electric actuator and a sprayer. The hydraulic system is for pressurizing a hydraulic fluid. The hydraulic actuator is powered by the hydraulic system. The electric actuator controls actuation of the hydraulic actuator by the hydraulic system. The sprayer is actuated by the hydraulic actuator.

Abstract: A clamp is secured to a displacement pump, and the clamp includes an axial ring and a tightening ring. The axial ring is mounted above the tightening ring, and the axial ring is configured to align the displacement pump during mounting and to limit the stoke of a pump rod within the displacement pump. The tightening ring may be tightened such that the axial ring and the tightening ring exert a clamping force on a drive housing, which secures the displacement pump to the drive housing. The tightening ring may receive a projection extending from the drive housing to provide structural support to the drive housing.
