Flow distributor for controlling two-way actuators with two short length control spools, comprises five port two position distribution valve

摘要

The distributor (10) consists of a housing (12) in which are fitted two spools (48,49) which move between two positions to connect fluid under pressure between working ports (36,38) and a feed (42) and discharge (40) port. The two spools (48,49) are placed in two separated drillings (22,24) parallel to each other and are connected to the working ports. These spools can be operated together, in the same direction, by actuating pistons (50,51) placed at either ends of the spools.
