Abstract: A bi-directional pump system that can be configured for a plurality of operating modes. The bi-directional pump system includes a plurality of bi-directional pumps each having their own valving system that are connected to a common high pressure manifold, a low pressure manifold and a suction manifold. Via the respective valve systems, each pump can be configured into: (1) a single-acting pumping mode; (2) a double-acting pumping mode; (3) an inactive free motion mode; and (4) an inactive rigid mode. One exemplary application of the bi-directional pump system is on an articulated wave energy conversion system that consists of three floating barges: a front barge, a center barge and a rear barge where the front barge and center barge are hingedly connected as are the center barge and the rear barge. A first set of the bi-directional pumps span the first hinge connection and the second set of bi-directional pumps span the second hinge connection. The bi-directional pump system intakes sea water and, using wave energy, outputs a high pressure flow of sea water for water desalination and/or for driving electrical generators.

Abstract translation: 可以配置为多个操作模式的双向泵系统。 双向泵系统包括多个双向泵，每个双向泵具有连接到公共高压歧管，低压歧管和吸入歧管的其自身的阀门系统。 通过相应的阀门系统，每个泵可配置成：（1）单作用泵送模式; （2）双作用泵送模式; （3）非活动自由运动模式; 和（4）无效刚性模式。 双向泵系统的一个示例性应用是关节式波浪能量转换系统，其由三艘浮式驳船组成：前驳船，中驳船和后驳船，其中前驳船和中驳驳船以中心方式铰接连接 驳船和后驳船。 第一组双向泵跨越第一铰链连接，第二组双向泵横跨第二铰链连接。 双向泵系统进入海水，并使用波浪能量输出高压海水来进行海水淡化和/或驱动发电机。
