PERFEZIONAMENTO NELLE VALVOLE ROTATIVE |
摘要 |
<p>A rotary valve, and more particularly a rotary directional control valve having a rotatable valve member operable by a two-stage operating lever providing a relatively long lever arm and an intermediate shorter lever arm. Solenoid-actuated actuator members are movable along a line for engagement with the shorter lever arm when the operating lever is in a neutral position extending in a direction generally normal to said line and for engagement with the relatively long lever arm when the operating lever is at a substantial angle to said line whereby a solenoid of medium force and moderate length stroke can be utilized in returning the operating lever to the neutral position.</p> |
