Abstract:
1. An internal locking apparatus comprising: a source of hydraulic fluid, an electronic control system having a power supply, and a hydraulically activated locking system including a pump, a solenoid valve, a cylinder, a locking member and shaft, where the hydraulically activated locking system is in fluid communication with the source and in electrical communication with the electronic control system, where the source, the electronic control system and the hydraulically activated locking system are all disposed in the interior of an enclosure, where the internal locking apparatus is mounted so that when the hydraulically activated locking system transitions between a locked position and an unlocked position or vis-a-versa, the hydraulically activated locking system locks or unlocks an opening to the enclosure and where the electronic control system provides power via the power supply to the hydraulically activated locking system causing the pump to pump hydraulic fluid into or out of the valve to effectuate the transition and where the hydraulic fluid is supplied by or returned to the source during a transition between the two positions.
