摘要： In a radial piston pump (2), which has pump elements (10) arranged radial in the pump housing (7) and which in turn have an inlet valve (11) and an outlet valve (12) activated by the medium, the valves (11, 12) are disposed at the outer side of the pump elements (10) whereby the inlet valves (11) are arranged coaxial relative to the pump piston (13). All inlet valves (11) are connected to a joint intake channel (20) that leads around the outside of the pump housing (7). To achieve a simple, flexible and operationally dependable design with a high degree of efficiency and low noise emission, the pump elements (10) are inserted from the outside and held in place in a bore (16) of the pump housing (7) as a complete unit, consisting of a cylinder barrel (15), a pump piston (13) and an inlet valve (11), and the joint inlet channel (20) is designed as a groove (21) that is open to the outside, which is covered with a fitted sealing member (22) after mounting of the pump element (10) onto the pump housing (7), and whereby said channel (20) is connected with the tank (4) via at least one bore (23) in the pump housing (7).
摘要翻译：在径向活塞泵（2）中，其具有径向设置在泵壳体（7）中的泵元件（10），并且还具有由介质启动的入口阀（11）和出口阀（12），所述阀（11,12）设置在泵元件（10）的外侧，由此入口阀（11）相对于泵活塞（13）布置成同轴。所有入口阀（11）连接到围绕泵壳体（7）的外部引导的接头进气通道（20）。为了实现具有高效率和低噪声发射的简单，灵活和可操作地可靠的设计，泵元件（10）从外部插入并且保持在泵壳体（7）的孔（16）中的适当位置，如由缸筒（15），泵活塞（13）和入口阀（11）组成的完整单元，并且联接入口通道（20）被设计为对外部开放的凹槽（21）其在将泵元件（10）安装到泵壳体（7）上之后被安装的密封构件（22）覆盖，并且由此所述通道（20）经由至少一个孔（23）与罐（4）连接）在泵壳体（7）中。

摘要： A high pressure pump. The pump comprises a fluid end assembly supported on a power end assembly. The power end assembly is modular and held together by a first set of stay rods. The fluid end assembly comprises a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a housing made of multiple-piece construction. One or more pieces of the housing are configured to having a second set of stay rods attached thereto. The second set of stay rods interconnect the fluid end assembly and a power end assembly and a vertically offset from the first set of stay rods.

The fluid routing plug is installed within a horizontal bore formed in a fluid end section and is configured to route fluid between an intake and discharge bore. The fluid routing plug comprises a plurality of first and second fluid passages. The first and second passages do not intersect and are offset from one another. The first fluid passages are configured to direct fluid delivered to the horizontal bore from intake bores towards a reciprocating plunger. The second fluid passages are configured to direct fluid pressurized by the plunger towards a discharge bore.
