Marine transmission actuator

A hydraulic valve, such as a rotary valve, is connected in fluid communication with a hydraulic actuator that, in turn, causes a clutch to move between forward, neutral, and reverse gear positions. A marine transmission is caused to shift between these gear positions in response to movement of a spo...

Zusammenfassung:A hydraulic valve, such as a rotary valve, is connected in fluid communication with a hydraulic actuator that, in turn, causes a clutch to move between forward, neutral, and reverse gear positions. A marine transmission is caused to shift between these gear positions in response to movement of a spool of the hydraulic valve, which can be a rotary valve. Movement of the valve causes an actuator to move to the selected gear position and maintain that gear position until a subsequent movement of the hydraulic valve.
