    Abstract: A wear sleeve is removably mounted on a piston rod. The piston rod includes a piston cap, a piston rod body, and a piston head, with at least one of the piston cap and the piston head being removable from the piston rod body. The wear sleeve is disposed over the piston rod body and prevents the piston rod from contacting dynamic seals disposed within a pump. The wear sleeve is mechanically secured in a cylindrical recess on the piston rod between a cap shoulder of the piston cap and a head shoulder of the piston head.

    Abstract: A spray gun includes a valve cartridge configured to be axially installed and removed as a single piece. The valve cartridge includes the wear components of the spray gun. A trigger of the spray gun is configured to actuate a slider of the valve cartridge to control spraying by the spray gun. The trigger includes arms that are mounted to the spray gun by a pivot mechanism. The pivot mechanism can be disengaged from the arms to allow the trigger to slide between a spray position, where the trigger prevents forward axial movement of the valve cartridge, and a repair position, where the valve cartridge can move axially forward. The trigger also includes upper and lower portions that are movable relative to each other, such that the length of the trigger can be adjusted.

    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 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.

    Abstract translation: 夹具固定在排量泵上，夹具包括轴向环和紧固环。 轴向环安装在紧固环的上方，并且轴向环被构造成在安装期间对准排量泵并且限制位移泵内的泵杆的行程。 紧固环可以被紧固，使得轴向环和紧固环对驱动壳体施加夹紧力，其将排量泵固定到驱动器壳体。 紧固环可以接收从驱动器壳体延伸的突起，以向驱动器壳体提供结构支撑。
