HYDRAULICALLY ASSISTED RAT ACTUATOR LATCH MECHANISM
First Claim
1. A ram air turbine actuator comprising:
- a housing;
at least one solenoid;
a latch mechanism operably connected to the at least one solenoid and located within the housing, the latch mechanism in operation moves from a first position to second position when the at least one solenoid is activated; and
a hydraulic pressure system operably connected to the latch mechanism, the hydraulic pressure system in operation moves the latch mechanism from the second position to the first position using hydraulic pressure from a hydraulic fluid, when the at least one solenoid is deactivated, wherein the hydraulic pressure system is located within the housing,wherein the hydraulic pressure is relieved when the latch mechanism is in the first position.

Abstract
A ram air turbine actuator having: a housing; at least one solenoid; a latch mechanism operably connected to the at least one solenoid and located within the housing, the latch mechanism in operation moves from a first position to second position when the at least one solenoid is activated; and a hydraulic pressure system operably connected to the latch mechanism, the hydraulic pressure system in operation moves the latch mechanism from the second position to the first position using hydraulic pressure from a hydraulic fluid, when the at least one solenoid is deactivated. The hydraulic pressure system is located within the housing. The hydraulic pressure is relieved when the latch mechanism is in the first position.
