The sealing grid is for a rotary piston mechanism having a multi-profile rotor forming apex portions, which rotor is supported for planetary rotary movement in a housing cavity. The sealing grid comprises an apex seal assembly carried in each of the apex portions of the rotor, which assembly includes an apex seal blade. Also forming part of the sealing grid are apex seal pins disposed in the opposite side faces of the rotor and at each of the apex portions. The grid additionally includes side gas seal strips carried in each of the opposite side faces of the rotor. One end portion of each side gas seal strip is disposed in abutment against an apex seal blade at one apex portion while the opposite end portion engages the apex seal pin located at an adjacent apex portion. The grid further includes a biasing means for each side gas seal strip for urging the associated side gas seal strip in an endwise direction and into abutment against the apex seal blade associated therewith.

Sealing grid for a rotary piston mechanism

A rotary combustion engine having a fuel nozzle for discharging fuel into each working chamber just prior to combustion and in which means are provided for increasing the width of the spray angle of the fuel discharged by said nozzle as the quantity of fuel discharged by the nozzle into each working chamber is increased.

Stratified charge rotary engine with variable spray angle fuel nozzle

A rotary combustion engine designed for operation as a stratified charge engine with two separately controllable fuel injection means combined into a single unitary fuel injection nozzle structure.

Dual fuel injection nozzle

A rotary combustion engine designed for operation as a stratified charge engine in which a relatively lean fuel-air mixture is supplied to each engine working chamber through the main air intake port and in which just prior to combustion in each engine working chamber, a relatively-rich, high-pressure, fuel-air mixture is supplied to each working chamber through individual passages in the rotor for each working chamber.
