Abstract

With a solenoid energized, the rod 3, the sleeve 1 and the piston 2 are pushed down to exhaust fluid from A through ports 7 and chamber 4 to E. A bias force, the difference between the force, executed by fluid from P through the chamber 5 on sleeve 1 and plug 6, and the force, executed by fluid from P on piston 2, which has slightly smaller diameter than the sleeve 1, is ineffective.

Jet-Assisted Sleeve Valve

With a solenoid energized, the rod 3, the sleeve 1 and the piston 2 are pushed down to exhaust fluid from A through ports 7 and chamber 4 to E. A bias force, the difference between the force, executed by fluid from P through the chamber 5 on sleeve 1 and plug 6, and the force, executed by fluid from P on piston 2, which has slightly smaller diameter than the sleeve 1, is ineffective.

When the solenoid is de-energized, the bias force raises sleeve 1. Ports 7 are closed and ports 8 open into annular recesses connected with A. Because ports 8 are at an acute angle, the jet reaction force assists the static fluid force.

Small solenoids are utilized. The conditions of pressure and exhaust in A are rapidly established.
