Abstract

An I.C. engine comprises a working chamber defined by a casing, or "barrel", B1 and a rotor 3 fixed to a power-output shaft 4, the working chamber being swept by vanes 1, 2 pivotally mounted on the rotor. Rotary valves in chambers VC1, VC2 control ports c, b, e and a transfer tube f, the valve in the chamber VC2 being furnished with a spring-loaded ball g1 to obturate the tube f while the port e is open. Fuel-air mixture is inducted through the port c by the vane 1 and compressed by the vane 2, the compressed mixture being thereafter transferred to the space behind the vane 1 through the pipe f and ignited by a sparking plug at p. Exhaust gases are discharged through the port e. <IMAGE>

Description

SPECIFICATION L.D.O. RV2+2 I.C. Engine This engine is of the hinged vane type. It also has rotary valves. Rotor housing 3 turns clockwise inside B1. Barrel RV in VC1 turns A to C. C. is fuel.

Air intake rotor vane 1 draws in fuel air to chamber via b port until vane 2 passes port b valve in VC1 turns FA. b. RV in VC 2 is in position shown in Fig. 2. Vane "2" pushes and compresses mixture into port HD up to bypass tube f and back to chamber in barrel via port b. Vane 1 has turned full circle and mixture is in space between port b and vane 1. P has P 1, plug ignition this fires sending vane 1 round when G1 ball valve has closed in b port to prevent expansion of gasses entering f bypass tube.

Expanded gasses pushes vane 1 round followed by vane 2.

RV in VC2 has turned h to e, exhaust outlet and G 1, ball valve is in cup at end off, bypass tube sealing f and allowing vane to push gasses out of e port in VC2, end of cycle.

This engine is of a new hinged vane type and has rotary valves and fly wheel timing.

Fig. 1 shows external features. C is fuel intake and a carburettor or fuel injector would be fitted.

P is plug hole for ignition.

VC1 and VC2 valve chambers are also shown in Figs. 2, 3, and 6, e in Fig. 1 is exhaust outlet FL1 and FL2. Part of split barrel, the two sections bolt together and this is to make construction and servicing simple.
