摘要： A rotary piston of a rotary piston internal combustion engine has radially and inner and outer annular seals carried within grooves of the rotary piston thrust surface axially facing the engine casing sidewall with the axial end face of the oil seal tapering radially outwards relative to the engine sidewall and forming lip angles between the tapered end wall of the seal such that the lip angle for the outer seal is between 1.degree. and 3.degree., the lip angle for the inner seal is between 3.degree. and 5.degree., and the spring biasing force acting on the radially outer seal is less than that acting on the radially inner seal. Preferably, an oil removal bore is formed in the land portion between the grooves for return of the oil delivered thereto by action of the oil seal to the oil pan of the engine.

摘要： A speed control system for an engine cooling fan has a planetary gearset, variably establishing a ratio between input and output speeds, and a hydraulic controller for changing the speed ratio according to engine operating conditions. Either one of a sun gear and pinion gear constitutes an input gear connected to an engine output of the engine. The other one of the sun gear and pinion gear is operationally coupled to a hydraulic control and a ring gear constitutes an output gear driving a rotary body. The hydraulic controller applies and varies an operational resistance to the planetary gearset according to engine operating conditions so as to cause it to vary the ratio of input and output speeds.

摘要： A rotary piston engine has a housing structure which includes a peripheral wall, having a trochoidal inner surface, and end walls secured to the peripheral wall with the latter situated therebetween. A rotor, having each end face formed with at least one set of side seal grooves and at least one oil seal groove, is housed within the housing structure for planetary motion. For avoiding leakage of blowby gas from any one of working chambers defined between the rotor flanks and the trochoidal inner surface into the inside of an oil seal in the oil seal groove past side seals in the side seal grooves, an annular gas groove is formed on at least one end face of the rotor. This annular gas groove is communicated to the oil seal groove by means of a passage formed in a partition wall separating the gas groove from the oil seal groove. The blowby gas collected in the gas groove can be recovered in the intake chamber through an intake port, provided in eitheror both of the end walls, during the planetary motion of the rotor.

摘要： A corner seal member for use in a rotary internal combustion engine is constructed with an apex seal groove and an elongated cavity. The elongated cavity forms a thin wall having a substantially semicircular cross-section in the opposite side of the apex seal groove. The gas pressure delivered into the elongated cavity is advantageously used for urging the corner seal towards the inner surface of the corner seal groove, thereby preventing the gas pressure from leaking into an adjacent working chamber.
