Title: Port cover for ramjet engine
Inventor: SAITO TAKEO
IPC: B64G1/40
Filed: 1992-04-08
Abstract: PURPOSE:To ensure the strength against the internal pressure and avoid occurrence of damages at the time of dismembering and scattering divisional ring pieces, by assembling a plurality of such divisional ring pieces into a concave bridge like configuration, binding and retaining the assembled structure as it stands, and releasing it. CONSTITUTION:When an airframe is launched and a propellant 6 is burnt out, an electric current is carried to an electric wire 11a whereupon a detonator of a separation nut 11 is crashed. As a result, a screw 10 is removed with the result that a port cover body 9 is opened. Port covering pieces 9a to 9d thus made open are caused to pass through a combustion chamber 3 due to the ram pressure of an air taken in from an air intake duct 1a, to be backwardly scattered in a dismembered manner. More specifically, after the port cover body 9 are bound and retained by the screw 10, a separation nut 11 and a retainer 12 which constitute a binding/retaining means, the separation nut 11 which concurrently serves as a releasing means is bursted as the necessity arises, to cause bursting and scattering of the port covering pieces. This enables avoiding various damages attributable to the port 9a to 9d.

Abstract: PURPOSE:To reduce the number of pumps to one unit alone, by selecting rotation of a motor in both c.w. and c.c.w. directions, and feeding a washer liquid in a way of selecting it to both front and rear sides. CONSTITUTION:When a washer liquid is fed to window glass at the front side, a motor 2 is rotated clockwise. If so, an impeller 4 is rotated clockwise as well, and thereby pressure is produced in two discharge ports, but with relation to the rotational direction and these discharge ports, high pressure is produced there by oneside of these discharge ports. This pressure is conducted to inflow ports 9A and 9B of a selector valve 7, and since the inflow port 9A becomes higher pressure than the inflow port 9B, a float valve 8 is forcedly pressed to the side of the inflow port 9B, closing the inflow port 9B and an outflow port 10B. And, the washer liquid flows into an operating chamber from the inflow port 9A, and it is fed to a washer nozzle 11A at the front side from an outflow port 10A through a hose 24.
