<p>A pneumatic ejector device suitable for use in an aerial bomb ejection system, in which pivotably operable jaws for gripping the bomb or other device are operatively interconnected to a pneumatically operated piston which engages with the bomb to effect positive release. The piston is contained within a gas tight cylinder and a radial clearance is provided therebetween to allow for gas leakage to both sides of the piston. The piston is locked in the loaded position by means of a spring and ball detent and is "armed" by charging air or other gas under pressure into the cylinder. Ejection is achieved by releasing gas pressure from the lower side of the piston at a rate in excess of the rate of leakage past the piston, by means of a solenoid controlled release valve.</p> |
