Abstract: A high-pressure, plunger-type liquid pump (10) including a liquidmanifold (16) that includes a plunger chamber in the form of an axial cylindrical bore portion (24) for slidably receiving a pressurizing plunger (20), and that also includes a valve chamber (42) coaxial with the plunger chamber (24) and in communication therewith for removably receiving a cartridge-type flow control valve (72, 161). The liquid manifold (16) includes a closure plug (36) to close the valve chamber (42). The cartridge-type valve (72, 161) is slidably received in the valve chamber (42) for enabling removal of the cartridge-type valve (72, 161) from the liquid manifold (16) without the need for separating the liquid manifold (16) from the pump drive housing (12). The cartridge-type valve (72, 161) is of a structure that includes in-line, axially spaced suction (100, 176) and discharge (136, 162) valves that are each spring biased into closed positions. High-pressure liquid is confined within a valve housing body (72, 160) that contains the suction and discharge valves, to minimize damage to the liquid manifold (16) as a result of pressure fluctuations and high-pressure flows. The cartridge-type valve (72, 161) is removable from the manifold (16) without the necessity of removing or even separating the manifold (16) from the pump drive housing (12).

Abstract translation: 一种高压柱塞式液体泵（10），包括液体歧管（16），其包括呈轴向圆柱形孔部分（24）形式的柱塞室，用于可滑动地接收加压柱塞（20），并且还包括 与柱塞室（24）同轴并与之连通的阀室（42），用于可拆卸地接收盒式流量控制阀（72,161）。 液体歧管（16）包括用于关闭阀室（42）的封闭塞（36）。 盒式阀（72,161）可滑动地容纳在阀室（42）中，以便能够从液体歧管（16）移除盒式阀（72,161），而不需要分离液体歧管（ 16）从泵驱动器壳体（12）移动。 盒式阀（72,161）的结构是包括线性间隔开的吸入（100,176）和排出（136,162）的阀，每个阀弹簧偏置到关闭位置。 高压液体被限制在包含吸入和排出阀的阀壳体（72,160）内，以使压力波动和高压流动对液歧管（16）的损伤最小化。 盒式阀（72,161）可从集管（16）移除，而不需要从歧管（16）移除或甚至分离歧管（16）。
