Abstract
Official abstract text for this publication.
An energy-saving valve includes a spool-driving unit which changes the position of a spool to a position at which compressed air is discharged from a first output port without pressure control and includes a pressure control unit which changes the position of the spool to a position at which compressed air is discharged from a second output port in a predetermined pressure level due to pressure control. The pressure control unit includes a pressure control piston, a pressure-receiving surface which enables air pressure in the second output port to act on the pressure control piston, a cylinder chamber, a pressure control channel, and an elastic member which applies biasing force to the pressure control piston in a direction opposite to the action of air pressure on the pressure-receiving surface to determine pressure.
First claim
Opening claim text (preview).
The invention claimed is: 1. An energy-saving valve comprising: a main valve body including a first end and a second end as two ends in a direction of an axis, a valve hole extending in the direction of the axis, and an air-supplying port, a first output port, a second output port, and air-discharging ports each being in communication with the valve hole; a spool slidably inserted into the valve hole and including channels through which the first output port is in communication…
