摘要:
A cable cutter assembly (200) for an aircraft (102) hoist is disclosed, and includes an actuator assembly (210) (e.g., at least one pressurized fluid cavity (248), a first outlet port (228), and a solenoid (240) that includes a coil (270) and an armature (290)). The armature (290) is movable between closed and open positions relative to the first outlet port (e.g., via an actuation force), with the armature (290) engaging the first outlet port (228) for the closed position (e.g., a valve seal (304) incorporated by the armature) and being spaced from the first outlet port (228) for the open position. A cutter (326) body (322) includes a cutter body (322) cavity (324) that is fluidly connected with the first outlet port (228). A cutter (326) is movably disposed within the cutter body cavity (324). Disposing the armature (290) in the open position (e.g., via energizing the coil) fluidly connects the pressurized fluid cavity (248) with the cutter body cavity (324) to move the cutter (326) in a cable (106, 360) cutting direction.
