Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lubricating device A of a rotary piston engine 1 for supplying oil to a trochoid inner peripheral surface 2a of a rotor housing 2 which satisfies lubrication requirement of each gas seal part in an outer periphery and side part of a rotor 6 and suppresses oil consumption. SOLUTION: The device has a center nozzle 41 at a substantially center in a rotor width direction on a trochoid inner peripheral surface 2a and side nozzles 40 on both sides of the nozzle, and includes a first and second oil pumps 31, 32 for respectively supplying oil to each nozzle 40, 41. In a low-load and low-speed rotation region, the second oil pump 32 is activated to supply oil to the center nozzle 41 only. In the other operating regions, both pumps 31, 32 are activated to supply oil through both nozzles 40, 41. COPYRIGHT: (C)2008,JPO&INPIT
