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： An improved air compressor is provided. The air compressor includes a cylinder block having a head deck that defines a piston bore for reciprocal movement of a piston therein. The head deck further includes first and second ramped surfaces that slope downward toward the peripheral edge of the piston bore. A valve plate is in direct contact with the upper surface of the head deck, the valve plate having a leaf valve. During an intake stroke of the piston, the leaf valve deflects downward into direct engagement with the first and second ramped surfaces. Because the air compressor lacks a lower gasket between the valve plate and the head deck, the cost and assembly time associated with the lower gasket are eliminated.

摘要： A fluid routing plug for use with a fluid end section. The fluid end section being one of a plurality of fluid end sections making up a fluid end side of a high pressure pump. The fluid routing plug is installed within a horizontal bore formed in a fluid end section and is configured to route fluid between an intake and discharge bore. The fluid routing plug comprises a plurality of first and second fluid passages. The first and second passages do not intersect and are offset from one another. The first fluid passages are configured to direct fluid delivered to the horizontal bore from intake bores towards a reciprocating plunger. The second fluid passages are configured to direct fluid pressurized by the plunger towards a discharge bore.

摘要： A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.

摘要： A multi-piece fluid end that can be produced with fewer raw materials and at a lower cost. In one embodiment, a fluid end is formed from a first body attached to a separate second body. Their respective external surfaces may be engaged flushly, partially, or via one or more spacer elements. In some embodiments, the body pieces are flangeless to reduce stress on the fluid end. The second body may have a plurality of bores that are alignable with a plurality of corresponding bores formed in the first body. The second body may be connected to a power end using a plurality of stay rods. In other implementations, more than two body pieces may be utilized.

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.
