Aircraft hatch emergency opening actuator including opening delay means

Aircraft hatch emergency opening actuator, comprising:

• a cylinder arranged to be connected to said hatch at one of its ends and at its other end to a reference frame of the aircraft to which said hatch is connected,
• fluid means for feeding said cylinder for emergency opening of the hatch,
• means for injection of said fluid means at a first point of a first fluid circuit feeding said cylinder for emergency opening of the hatch, said injection means being able to adopt two positions:
• a first position, called the rest position, in which said fluid means are isolated from said cylinder,
• a second position, called the active position, in which said fluid means are injected at said first point of said first fluid circuit,
• means for delaying the injection of said fluid means into said cylinder, which delay means include a mobile element in said first fluid circuit, disposed between said first point and said cylinder, delaying opening of said first circuit when said injection means are in the active position, the injection delay being determined by a time of movement of said mobile element.
