FIELD: engines and pumps. ^ SUBSTANCE: proposed engine comprises housing with intake opening and working chamber, two-lobe rotor with larger and smaller axes of symmetry, and pump with intake opening. Two-lobe rotor is fitted on camshaft. Pump is fitted on camshaft and incorporates two-lobe rotor. Engine and pump housing inner chamber outlines represent circumference conchoids. Pump intake opening is made in pump housing. Inlet opening top edge matches the lobe of pump rotor at dead center. Exhaust opening is made in engine housing. Air-inlet valve is arranged on engine working surface in the zone of combustion chamber. Slide valve is arranged between engine and pump housing and has holes perpendicular to its axis and communicated by channel. One hole is arranged opposite bypass valve in engine housing while another one is arranged opposite bypass valve in pump housing. Combustion chamber is arranged between engine rotor top working surface and engine chamber working surface when rotor stays at dead center by setting the angle between radii and engine and pump cams. ^ EFFECT: higher efficiency and reliability. ^ 1 cl, 6 dwg |
