A lubricant proportioning pump having a delivery piston controling the pumping operation, rotatable about its longitudinal axis by way of a step-down transmission and movable to and fro in lengthwise direction by means of a cam track held against a fixed guide by spring action, while an adjustable stop cooperates with the piston and limits its stroke, the adjustable stop having an expansion element arranged therein for varying the stroke of the piston as a function of temperature.

Lubricant proportioning pump

The improved ignition means for a rotary combustion engine of the type, having a rotor which planetates within a multi-lobed housing cavity which is partly defined by an inner peripheral wall surface, comprises a spark plug having an axis which extends substantially normal to the peripheral wall surface and has means forming a spark-gap disposed in an ante-chamber adjacent the inner peripheral wall surface. An ignition channel of small size in relation to the size of the ante-chamber extends from the ante-chamber through the peripheral wall surface and is disposed in offset substantially parallel relationship with the longitudinal axis of the spark plug.
