摘要： There is disclosed a pump, in particular a reciprocating pump. In one embodiment, a reciprocating pump (10) is disclosed which comprises an actuating cylinder (12); an actuating piston (16) mounted for reciprocating movement within the actuating cylinder; a discharge cylinder (52); a sleeve (40) releasably mounted within the discharge cylinder, to thereby define an operating diameter of the discharge cylinder; and a discharge piston (30) coupled to the actuating piston and mounted for reciprocating movement within the sleeve to successively draw fluid into and discharge fluid from the discharge cylinder. There is also disclosed a sleeve for such a pump, and a method of changing output flow from such a pump.

摘要： There is disclosed a valve assembly for a pump such as a dual-piston reciprocating pump, and to such a pump incorporating a valve assembly.
In one embodiment, a valve assembly (10) is disclosed which includes a valve main body (98); a valve member (100) mounted for movement within the valve main body, to control the supply of an actuating fluid to a pump (10); a main valve inlet (81) formed in the valve main body, through which actuating fluid is supplied to the valve main body; and an inlet valve (83) for controlling the flow of actuating fluid through the main valve inlet into the valve main body. Providing a valve assembly with such an inlet valve facilitates accurate control of the flow of actuating fluid into the valve assembly. This in turn facilitates control of the flow of actuating fluid to a pump, thereby permitting one or more operating characteristics of the pump to be varied.摘要翻译： 公开了一种用于诸如双活塞往复泵的泵的阀组件，并且涉及包含阀组件的这种泵。 在一个实施例中，公开了一种阀组件（10），其包括阀主体（98）; 阀门构件（100），所述阀门构件（100）被安装用于在所述阀门主体内移动，以控制致动流体向泵（10）的供应; 主阀入口（81），其形成在阀主体中，致动流体通过该主阀入口供应到阀主体; 和用于控制致动流体通过主阀入口流入阀主体的流入阀（83）。 提供具有这种入口阀的阀组件便于精确控制进入阀组件的致动流体的流动。 这又便于控制致动流体到泵的流动，由此允许改变泵的一个或多个操作特性。
