Abstract: 1,252,775. Air cushion vehicles. BERTIN & CIE. 14 Nov., 1968 [17 Nov., 1967], No. 54109/68. Heading B7K. In a ground effect machine in which a fluid pressure cushion is produced within a plenum chamber defined by walls 3 depending from a base, there is also provided a resiliently deformable wall 4 which forms an upper wall of the plenum chamber and also with the base 1 a chamber of variable volume, there being means for exerting within the variable volume chamber a pressure P 1  on the deformable wall which is greater than the normal operating pressure P of the fluid cushion. A momentary increase in the cushion pressure thus/deforms the deformable wall giving a temporary increase in the volume of the plenum chamber to restore the cushion pressure. In one embodiment (Fig. 1) the chamber of variable volume is connected to a buffer chamber 7. A fan 5a supplies pressure fluid to both the plenum chamber and the variable volume chamber. A total pressure takeoff 6 faces the fan and feeds the buffer chamber 7. Alternatively (Fig. 4) the chamber of variable volume is connected to two sources of gas one at pressure P 2 >P and one at pressure P 0 #P. These sources also connect with a buffer chamber 19 which is sealed from the variable volume chamber by a spring loaded door when pressure in chamber 19 is greater than or equal to P 1 . In other embodiments the variable volume chamber is fed by gas from an injector., The injector includes an adjustable valve located in an orifice of variable area. If desired valves 21a, 21b, 22a, 22b, 23 can adjust the pressure in the variable volume chamber anywhere between P 2  and P 0 . The deformable wall 4 may be annular and is secured in fluid tight manner to wall 3. The pressure exerted on wall 4 in the variable volume chamber may be from one or more springs or by foam rubber. It is preferred that the vehicle has a plurality of plenum chambers each such chamber including a variable volume chamber.

The device shown comprises a flap 1 mounted in a box 7 on a vertically-displaceable pivot 2, the flap being biassed upwardly by a spring 6 and having a depending plate 9 cooperating with opposed different-height stops 3, 5 so that in the upper position of pivot 2 the stop 5 prevents anticlockwise rotation while in the lower pivot position the stop 3 is additionally engaged to prevent clockwise rotation. On approach of a vehicle from the left the flap 1 remains horizontal and is merely depressed slightly to the Fig. 2 position, thereby allowing vehicle passage, but approach of a vehicle from the right causes substantial clockwise rotation of the flap 1 to the Fig. 3 position wherein vehicle passage is obstructed. An additional obstructive flap 10 cooperating with a stop 11 and actuated by the flap I may be pivoted to the box 7. In a modification, Fig. 4 (not shown), the flap 10 and stop 11 are replaced by a flap (10a) pivoted to the flap (1) and anchored to the base of the box (7) by a wire link. The box may incorporate a microswitch for a counting mechanism. It is stated that the flap may be locked electromagnetically rather than mechanically.
