摘要： A reciprocating pump assembly has a pump housing with a crankshaft. A plunger is connected to the crankshaft for pumping a fluid through a cylinder. The cylinder has a fluid inlet port and an opening that provides access to the cylinder. A suction cover is mounted in the opening and has a hub that is coaxial with an axis of the suction cover. A suction valve stop is mounted adjacent one of the fluid ports and has a spring retainer. A column extends from the spring retainer, and a bushing is mounted to the spring retainer for engaging and being retained by the hub of the suction cover. The suction cover guides the suction valve stop in operation and, when the suction cover is removed from the opening, the suction valve stop is removable.

摘要： A pressure washer pump generally includes a pump housing that defines a cavity, an opening into the cavity and a bottom of the cavity generally opposite the opening. A valve assembly is disposed in the cavity through the opening. The valve assembly includes a cage member that contains a first valve mechanism. A plug member is received in the opening to fluidly seal the cavity of the pump housing. A compliant member is disposed between the plug member and the cage member. The cage member is disposed between the compliant member and the bottom of the cavity and spaced from the plug member.

摘要： Suction valve spring retainers mounted using an access bore plug are described for use in plunger pump housings having an offset access bore and incorporating structural features for stress-relief. These pump housing structural features accommodate access bore plugs that secure suction valve spring retainers that are internally located substantially centrally over the suction bore transition area of the plunger pump housing. Access bore plugs are secured in place on the pump housing using one or more threaded retainers. Plunger pumps so constructed are relatively resistant to fatigue failure because of stress-reducing structural features, and they may incorporate a variety of valve styles, including top and lower stem-guided valves and crow-foot-guided valves, in easily-maintained configurations. Suction valve spring retainers mounted in plunger pump housings may also incorporate a suction valve top stem guide. Further, certain structural features of access bore plugs may be dimensioned to aid in improving volumetric efficiency of the pumps in which they are used.

摘要： A drive mechanism for delivery of infusion medium has a coil and an armature moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is moveable axially within a piston channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. In the retracted position of the piston, a piston chamber is formed between the piston and a valve member and is filled with infusion medium. As the piston is moved to its forward position, the piston chamber volume is reduced and pressure within the piston chamber increases to a point where the pressure moves the valve member into an open position through an outlet.

摘要： A cylinder block assembly for a reciprocating pump includes a block body having a piston chamber that receives a piston of the reciprocating pump. The cylinder block assembly has an outlet valve assembly positioned within the block body that is positioned in fluid communication with the piston chamber. An outlet valve retainer retains the outlet valve relative to the piston chamber. The cylinder block assembly includes an inlet valve assembly extending through a side of the block body to the piston chamber. An inlet valve retainer also retains the inlet valve assembly relative to the piston chamber. A discharge passage extends from the outlet valve assembly to another side of the block body. A portion of the discharge passage extends between the inlet valve assembly and the inlet valve retainer.

摘要： A valve apparatus that has a longitudinal axis therethrough comprises a valve seat member, a valve closure member, a fluid flow path, and a screening member. The valve seat member comprises a hollow bore and a first frustoconical contact surface. The valve closure member comprises a body and a second frustoconical contact surface that is adapted to seal against the first frustoconical contact surface. The valve closure member is movable along the longitudinal axis of the valve apparatus. The fluid flow path extends through the bore of the valve seat member and between the valve seat member and the valve closure member. This fluid flow path is closed when the second frustoconical contact surface is sealed against the first frustoconical contact surface. The screening member is attached to at least one of the valve closure member or the valve seat member, and screens particles from fluid passing through the fluid flow path when the valve closure member approaches the valve seat member.

摘要： A bi-directional fluid valve apparatus comprising a valve member adapted to co-act with an annular shoulder at the end of a fluid bore, the valve member having two axial ends. A flat surface on a first end having a diameter greater than that of the shoulder is positioned with the flat surface abutting the axial end surface of the shoulder. At least two axially extending and circumferentially spaced apart ribs are on the second axial end thereof, each of the ribs terminating in an end surface. The ribs are positioned so that the end surfaces are in axial alignment with, and spaced a preselected distance from, the axial end surface of the shoulder. Hollow coil spring means are positioned within the recesses in register with the bores, and having a first end engaging one of the shoulders, and a second end engaging the at least three circumferentially spaced apart ribs and the second axial end of the valve member.
