Abstract: A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes an airflow controller for controlling the flow of the compressed air to a nozzle of the spray gun, a pressure regulator for regulating a pressure of the compressed air flowing to the hopper, and a relief valve between the pressure regulator and the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

Abstract: A piston rod for pumping paint includes an elongated cylindrical stem and a piston rod cap connected to the cylindrical stem. The cylindrical stem is formed from metal and has an outer diameter that is uniform along most or all of a length of the cylindrical stem. The piston rod cap is cylindrical and formed from metal. The piston rod cap includes an annular top portion that has an outer diameter that is larger than the outer diameter of the cylindrical stem, an annular bottom portion that has an outer diameter that is larger than the outer diameter of the cylindrical stem, and an exterior recess located between the annular top and bottom portions. The recess has an outer diameter that is smaller than the outer diameters of the annular top and bottom portions.

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 translation: 排量泵包括具有从泵杆的头部延伸的负载集中特征的泵杆。 泵杆的头部被接收在驱动连杆的槽内，并且驱动连杆被配置为接触负载集中特征。 使驱动连杆接触较小直径的负载集中特征减小了驱动力和泵杆中心之间的不对准，从而减少了泵杆所经受的侧向负载。 排量泵构造成用于流体分配系统。

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 translation: 泵杆具有从颈部延伸的头部，并且头部被容纳在驱动连杆的驱动槽内。 头部包括突起，并且具有小于头部区域的面积。 突起接触驱动槽的内表面。 驱动连杆可以包括与驱动连杆的中心线对准的突出部。 驱动连杆突起接触泵杆的头部。 突起提供了泵杆和驱动连杆之间的减小的接触面积，从而减少了泵杆上的任何侧向负载并增加了耐磨部件的使用寿命。

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 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.
