摘要： A high pressure pump. The pump comprises a fluid end assembly supported on a power end assembly. The power end assembly is modular and held together by a first set of stay rods. The fluid end assembly comprises a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a housing made of multiple-piece construction. One or more pieces of the housing are configured to having a second set of stay rods attached thereto. The second set of stay rods interconnect the fluid end assembly and a power end assembly and a vertically offset from the first set of stay rods.

摘要： A positive displacement pump is provided. The pump comprises at least one piston operable to be powered by a power source and to pressurize a fluid. The at least one piston comprises an at least partially hollow piston wherein a flow of fluid is induced into and through the piston and a surrounding piston chamber. The piston preferably comprises a direct-mounted outlet valve for controlling a flow of fluid into and out of the piston.

摘要： An improved air compressor includes a cylinder with a piston body and an air storage container. The air storage container can be detachably mounted to the cylinder to define a primary air chamber, and an auxiliary air chamber which can reduce the motion resistance of the piston body, so that the piston body can conduct reciprocating motion in the cylinder more smoothly. Furthermore, the cylinder has an open bottom that is divided into two halves according to a central vertical line (Y) of the cylinder, wherein one half of the open bottom is horizontal while the other half of the open bottom is slanted. When the piston body reaches the bottom dead center, the head of the piston body will be entirely within the cylinder and thus keep air-tight with the cylinder. Therefore, the performance of compressing air and the operational safety can be increased.

摘要： A fluid end includes a casing that defines a work space that includes a cross bore space and an inlet bore centered on an inlet bore axis and intersecting the cross bore space, the intersection of the inlet bore and the cross bore space at least partially defined by a first curved edge. An outlet bore is centered on an outlet bore axis and intersects the cross bore space, a plunger bore is centered on a plunger axis and intersects the cross bore space, a first angled surface is defined by the first curved edge, and a second angled surface is disposed adjacent the first angled surface such that the first and second angled surfaces cooperate to define a V-shaped groove having an exterior angle between 180 degrees and 270 degrees. An inlet spring retainer includes a first engagement portion, is orientable in a first orientation in which the retainer is movable from the inlet bore to the plunger bore and a second orientation in which the retainer engages the first and second angled surfaces to inhibit movement of the retainer.
