Abstract
PURPOSE: To considerably reduce force with which a spool valve is operated by making a liquid output of a spool valve eccentric with the spool center so as to create spool rotation in the open direction and thereby setting off a reactive rotation in the close direction due to squirt at the output.
CONSTITUTION: An electric motor 1 rotates a spool valve 4 through a connecting device 2 and a thread 3. As the spool is so driven, it is slid rightward (on the accompanying figure), causing a port to open accordingly. Fluid then flows through an input 7 into an output 8. Since the input 7 and output 8 are offset to the center of the spool 4, a reactive force which attempts to rotate the spool 4 in the open direction is created. That is, another reactive force created by squirt of fluid at the spool outlet in the close direction is cancelled by the first force. Force required to operate the spool can be further reduced to a considerable degree by forming the section of the shaft 6 as illustrated in the sketches 21W24.
