Abstract: According to one aspect, a pump assembly includes a fluid cylinder, and the fluid cylinder includes a fluid passage that defines a tapered internal shoulder of the fluid cylinder. The tapered internal shoulder defines a first frusto-conical surface. A valve controls flow of fluid through the fluid passage. The valve includes a valve seat, which includes a seat body disposed in the fluid passage, and a bore formed through the seat body and through which fluid flows. The seat body includes inlet and outlet end portions, wherein the fluid flows into the bore at the inlet end portion and flows out of the bore at the outlet end portion. The inlet end portion of the seat body defines a second frusto-conical surface. In one embodiment, the second frusto-conical surface engages the first frusto-conical surface to distribute and transfer loading.

Abstract translation: 根据一个方面，泵组件包括流体缸，并且流体缸包括限定流体缸的锥形内部肩部的流体通道。 锥形内肩部限定第一截头圆锥形表面。 阀门控制流体通过流体通道的流动。 阀包括阀座，其包括设置在流体通道中的座体，以及通过座体形成的孔，流体流过该孔。 座体包括入口端部和出口端部分，其中流体在入口端部处流入孔中并在出口端部处流出孔。 座体的入口端部分限定第二截头圆锥形表面。 在一个实施例中，第二截头圆锥形表面接合第一截头圆锥形表面以分布和转移负载。
