<p>A fluid translating device for a pressure fluid system comprising expansible chamber units, and working members therein, so combined and working in unison as to divide fluid from a source for delivery in equal parts to other sources. When the units are of even number the device is bidirectional in that it will divide flow when flow is in one direction in the fluid system or will combine flow when flow in the same system is in the opposite direction. Each unit (e.g., cylinder and piston) has three ports for communicating with a source and two additional ports respectively connected to a port communicating with the expansible chamber of another unit, whereby fluid from a source drives one working member (piston) which itself translates fluid to another source. In a preferred embodiment, two units valve each other, and effective ports are switched as a piston moves through a 90 DEG position.</p> |
