摘要： Differential coefficients of thermal expansion facilitate close approximation during cooling of a sintered cemented carbide tubular inlay preform (e.g., a first tubular portion) which is vacuum brazed within a corresponding tubular metal hull (e.g., a second tubular portion). Such a tubular inlay preform comprises at least one metal carbide and at least one nonvolatile cement which have previously been compressed and sintered in a predetermined shape. The tubular inlay preform's modulus of elasticity and thermal conductivity substantially exceed the corresponding parameters of the tubular metal hull, whereas the hull's coefficient of thermal expansion exceeds that of the preform. Longitudinal movement of a tubular inlay preform within a tubular hull may be limited by structural features of the hull and/or preform. Additionally, circumferential compression of a tubular inlay preform due to hoop stress in a corresponding tubular metal hull increases as the hull cools after vacuum brazing.
摘要翻译：差分的热膨胀系数在冷却被对应的管状金属外壳（例如，第二管状部分）内真空钎焊的烧结的硬质合金管状嵌体预制件（例如，第一管状部分）时有利于近似。这种管状嵌体预制件包括至少一种金属碳化物和至少一种预先被压缩并以预定形状烧结的非挥发性水泥。管状嵌体预成型件的弹性模量和导热率基本上超过了管状金属外壳的相应参数，而船体的热膨胀系数超过了预制件的热膨胀系数。管状嵌体预制件在管状船体内的纵向运动可能受到船体和/或预制件的结构特征的限制。另外，由于在相应的管状金属壳体中的环向应力的管状嵌入式预制件的周向压缩随着真空钎焊后的船体冷却而增加。

摘要： A valve body substantially symmetrical about a longitudinal axis has at least one internal space and comprises guide means and two separately formed portions joined by at least one cylindrical web. One or more passages spaced apart from the longitudinal axis allow fluid communication between at least one internal space and space external to the valve body. At least one internal space may be substantially filled with a substantially incompressible flowable substance to facilitate pressure equalization across the valve body. Forging or casting valve body portions to near-net-shape prior to joining minimizes machining necessary to achieve a final desired shape. Increased valve durability and reduced metal wear arise from reduced valve body weight and correspondingly reduced impact loading as the valve body moves to seal against a valve seat. Valve sealing may be aided by an elastomeric seal in a peripheral integral seal retention groove of the valve body.
摘要翻译：基本上围绕纵向轴线对称的阀体具有至少一个内部空间，并且包括引导装置和由至少一个圆柱形网连接的两个单独形成的部分。与纵向轴线间隔开的一个或多个通道允许至少一个内部空间和阀体外部的空间之间的流体连通。至少一个内部空间可以基本上填充有基本上不可压缩的可流动物质，以便于穿过阀体的压力平衡。在连接之前将锻造或铸造阀体部分接近网状，最小化实现最终期望形状所需的加工。增加的阀门耐久性和减少的金属磨损是由于阀体移动以密封阀座而减少阀体重量并相应减小的冲击载荷。阀密封可以通过阀体的周边整体密封保持槽中的弹性体密封件来辅助。

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 high pressure piston for use within a liner for a reciprocating pump comprises an elastomeric seal and an annular bearing ring. During the pump's pressure stroke at least a portion of the bearing ring elastically expands radially to narrow or close the extrusion gap, thus tending to block elastomer extrusion and establish sliding contact between the bearing ring's outer surface and the liner. An extrusion control groove located radially inward from the peripheral bearing ring contact surface of certain embodiments also tends to block elastomer extrusion. Under reduced pressure on the pump's return stroke, the bearing ring elastically contracts radially, slightly widening the extrusion gap. On the pump's return stroke the slightly wider extrusion gap allows cooling water directed generally toward the proximal flange of the piston hub to better cleanse, as well as cool, the liner wall.
摘要翻译：用于往复式泵的衬套内的高压活塞包括弹性密封件和环形轴承环。在泵的压力冲程期间，轴承环的至少一部分径向弹性膨胀以缩小或缩小挤出间隙，因此倾向于阻止弹性体挤出并且在轴承环的外表面和衬套之间建立滑动接触。从某些实施方案的外围轴承环接触表面径向向内定位的挤出控制槽也倾向于阻止弹性体挤出。在泵返回行程的减压下，轴承环径向弹性收缩，稍微加宽挤压间隙。在泵的返回行程上，稍微更宽的挤出间隙允许冷却水通常朝向活塞毂的近侧凸缘定向，以更好地清洁并冷却衬套壁。
