Abstract:
1. A control arrangement for a rotary piston engine, comprising: a housing having a runway formed by a single-curved trochoid; a two-cornered piston; and a guidance mechanism for rotating and sliding the piston relative to a side of the housing, the guidance mechanism including a guide track formed in the piston, a sliding block extending into the piston and guided by the guide track, and a pin having an axial throughbore through which fluid is guided into the piston; and wherein the pin includes a radial throughhole communicating between the axial throughbore and a periphery of the pin, the radial throughhole in the pin being located in a section of the pin which extends into the sliding block; wherein the sliding block is coupled to the pin and includes a plurality of inner connecting channels which guide fluid between the radial throughhole in the pin and channels in the piston; and wherein when the control arrangement operates and the pin movingly rotates within the sliding block so that the radial throughhole is in communication with at least one of the plurality of inner connecting channels of the sliding block and the sliding block further moves in the guide track so that the at least one inner connecting channel aligns with at least one channel of the piston, a fluid path is configured along which the fluid flows through the piston to a working room of the rotary piston engine, the fluid path comprising the axial throughbore of the pin, the radial throughhole of the pin, the at least one inner connecting channel of the sliding block, and the at least one channel of the piston.
