摘要： A pump assembly with valve-seat interface architecture configured to extend the life of pump components and the assembly. A valve of the pump assembly is equipped with a conformable valve insert that is configured with a circumferential component having the capacity to reduce the radial strain of its own deformation upon its striking of a valve seat at the interface within the pump assembly. The circumferential component may include a concave surface about the insert, a rounded abutment at the strike surface of the insert, or a core mechanism within the insert that is of greater energy absorbing character than surrounding material of the insert. Additionally, the valve seat itself may be configured for more even wear over time and equipped with a conformable seat insert to reduce wear on the valve insert.

摘要： Tapered valve guide and spring retainer assemblies are described for use in plunger pump housings that incorporate corresponding outwardly flared discharge and suction bores, as well as structural features for stress-relief. Plunger pumps so constructed are relatively resistant to fatigue failure because of stress reductions, 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. Besides forming a part of valve guide and spring retainer assemblies, side spacers may be shaped and dimensioned to improve volumetric efficiency of the pumps in which they are used.

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： Valve guide and spring retainer assemblies are described for use in plunger pump housings that incorporate structural features for stress-relief. These pump housing structural features accommodate correspondingly-shaped valve guides and/or spring retainers that are internally fixed in place using one or more non-threaded spacers. Plunger pumps so constructed are relatively resistant to fatigue failure because of stress reductions, 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. Besides securing valve guides and/or spring retainers, non-threaded spacers may be shaped and dimensioned to aid in further reducing stress and to improve volumetric efficiency of the pumps in which they are used.

摘要： A suction passage (1) and a discharge passage (2) for a to-be-transferred fluid are disposed in a pump body (3). A bottomed cylindrical bellows (6) is integrally coupled to the axial rear side of the pump body to form a closed space (7). The suction passage (1) has an upstream portion (1A) having a larger diameter and a predetermined passage cross section area, and downstream portions (1B) which are formed by branching the upstream portion into a bifurcated or Y-shape while reducing the passage cross section area. Two first small check valves (15) of the spring type in each of which the pressure receiving area is reduced in accordance with the reduced passage cross section areas of the smaller-diameter downstream portions (1B) are attached respectively to outlet portions of the smaller-diameter down-stream portions (1B) so as to be arranged in parallel. The outlets of the first check valves (15) are opened in the closed space (7).
