    • The present invention involves several different embodiments related to a crossover switching valve. The crossover switching valve is preferably designed to receive fluid from a reservoir, or other fluid source, and direct the inflow and outflow of the fluid between the valve and one or more pumps. In one embodiment, the valve is configured to provide a substantially continuous flow rate when used in connection with a double acting pump. In another embodiment, the valve preferably includes an inflow port, an outflow port, and first and second ports configured to be fluidly connected to at least one pump. Another embodiment of the present invention is at least one conduit that preferably provides fluid communication between the first and second ports. Yet another embodiment is a fluid director that is preferably configured to alter flow of fluid through the conduit.
    • 本发明涉及与交叉切换阀相关的若干不同实施例。 交叉切换阀优选地设计成从储存器或其他流体源接收流体,并且引导流体在阀和一个或多个泵之间的流入和流出。 在一个实施例中,阀配置成当与双作用泵结合使用时提供基本连续的流速。 在另一个实施例中,阀优选地包括流入端口,流出端口以及被配置成与至少一个泵流体连接的第一和第二端口。 本发明的另一个实施例是至少一个导管,其优选地在第一和第二端口之间提供流体连通。 另一个实施例是流体导向器,其优选地构造成改变通过导管的流体流动。
