Abstract: A folding trailing arm landing gear assembly having a main fitting configured to couple to a hinge positioned at a proximal end; a swing arm rotatably coupled at a proximal end to a distal end of the main fitting; a shock coupled at a distal end to a distal end of the swing arm; a bellcrank coupled at a distal end to a proximal end of the shock, and coupled at a proximal end to the main fitting; and a wheel coupled to the swing arm.

Abstract: A solenoid valve for controlling a fluid flow. The solenoid valve comprises an actuating member (101) moveable between a first position and a second position. Movement of the actuating member (101) in one direction effects opening of the valve and movement of the actuating member (101) in an opposite direction effects closing of the valve. The solenoid valve further comprises a biasing means (102) for biasing the actuating member (101) towards the first position; and an armature (103) moveable in response to energising/de-energising of the solenoid valve. Energising the solenoid valve is operable to move the armature (103) to engage the actuating member (101) and cause movement of the actuating member (101) to the second position against action of the biasing means (102).
