摘要： PURPOSE:To prevent entrance of oil, by a method wherein oil in oil steam passing an oil separator located between a power piston and a crank chamber is separated by passage of the oil through a pipe for cooling through which to intercommunicated two spaces partitioned by a shield plate 29. CONSTITUTION:A power piston 15 for a stirling engine is coupled to a crank in a crank chamber through a power piston rod 14. An oil separator 23 adapted to prevent entrance of oil from a crank chamber to an actuating space above the power piston is situated between the power piston 15 and the crank chamber. Though oildrops are removed through a filterlike oil separator, oil steam passes, and since the oil steam produces oildrops in an upper space, a shield plate 29 is situated in order to remove the oildrops. A first space 30a above the shield plate 29 and a second space 30b are intercommunicated through a pipe 28 for cooling which is cooled during passage of it within a jacket 16a for cooling, and oil steam produces oildrops for recovery.

摘要： PURPOSE:To lengthen the service life of a bearing by making a groove for applying a downward force onto the gas surrounding the rotary shaft of a rotary member upon rotation thereof. CONSTITUTION:A screw groove 19 is made in the outside face of a rotary shaft 2. The screw groove 19 is made such that it will apply downward force onto the gas surrounding the rotary shaft 2 during rotation thereof. Consequently, when the rotary shaft 2 rotates, the gas existing between the rotary shaft 2 and an inner tube 15 is subjected to the force for moving the gas in the direction of an arrow 20 thereby the oil vapor is prevented from passing between the rotary shaft 2 and the inner tube 15 and moving in the opposite direction from the arrow 20. Consequently, the service life of the upper bearing is lengthened.

摘要： PURPOSE:To obtain a simple, inexpensive lubrication mechanism utilizing pressure variance within a crank case by arranging a partition plate in a bottom part of the crank case to divide the said part into an oil reservoir part and an upper space above the said plate and providing the said plate with both an oil return valve and an oil supply valve. CONSTITUTION:When a power piston connected via a rod 14 to a crosshead 13 reciprocates within a cylinder 16, pressure within a crank case 1 varies. Therefore, dividing the inside of the crank case 1 with a partition plate 30 into a part for holding lubricant oil 21 and a gas space, and providing the partition plate 30 with an oil return valve 32 and an oil supply valve 33, pumping action is performed. Namely, the oil return valve 32 is opened when the pressure in the crank case 1 is higher than its means pressure to drop the lubricant oil 21 into the bottom part of the crank case bottom cover. When the pressure in the crank case 1 is lower than the mean pressure on the other hand, the oil supply valve 33 is opened to raise the lubricant oil 21 via an oil supply pipe 34.

摘要： PURPOSE:To effectively reduce the vibration of a vehicle body, by predicting the vibration mode of a vehicle body in accordance with the rotational speed of an engine and the weight of the vehicle body, and by controlling an actuator for applying damping force to the vehicle body in accordance with the result. CONSTITUTION:An engine rotational speed detecting circuit 8 is connected to an engine ignition pulse terminal 7, and a control circuit 9 in a control section 18 obtains a waveform having an amplitude and a phase which correspond to the engine rotational speed detected by the circuit 8. This waveform is compensated in accordance with the weight of a vehicle body detected by a weight detecting circuit 13 connected to a strain gage weight detector 12, and is then amplified by a power amplifier circuit 10, and thereafter is delivered to an actuator 6 which is constituted such that electromagnetic force that is generated when a coil 63 is energized, is transmitted to a casing 68 fixed to the vehicle body through a coil support 64. Thus, it is possible to aim at cancelling out torque variations caused by the rotation of the engine 1 with the use of the force from the actuator 6 to reduce the vibration of the vehicle body 4.

摘要： PURPOSE:To improve a feeling of driving comfortableness and durability in a controller, by driving an actuator with a detecting signal out of a vibration detector, while detecting a driving state, and interconnecting an empty space, where an elastic body exists, to an engine negative pressure part at the time of driving but selecting it to a positive pressure part at the time of stoppage. CONSTITUTION:An engine is discriminated as it is at idling or driving by an engine speed detector while a three-way valve is selected to where it should be, and a negative pressure port 25 is interconnected to a suction pipe at the time of driving and to a positive pressure part at the time of idling, respectively. At driving, an empty space 35 is made to come into suction pressure whereby a pressure differential between these spaces 35 and 36 grow large, pushing up a pressing device 23, and thereby a movable mass body 9 is locked thereto. On the other hand, at idling, the space 35 is interconnected to the positive pressure part, making the pressure differential between these spaces 35 and 36 dwindle away to nothing, whereby the pressing device 23 is pushed up and the body 9 is opened free, thereby making an actuator 6 come into a state of being operated. And, since the body 9 comes to a stationary state at the time of driving, any impact to a casing 18 due to vibrations in the body 9 and disturbance is avoided, thus no noise happens and service life is prolonged.

摘要： PURPOSE:To improve a feeling of driving comfortableness and durability ever so better, by driving an actuator with a vibration detector, while detecting a driving state, and selectively interconnecting an empty space, where an elastic body energizing a pressing device of a movable mass body is situated, to an engine negative pressure generating part and a positive pressure part. CONSTITUTION:An electric signal of the varying torque disturbance of an engine 1 detected by a vibration sensor 7 is inputted into a control circuit 8, feeding driving power of an actuator 6, and controlling force of the actuator 6 is impressed on a direction of damping vibrations in a car body 4, thus vibrations in the car body 4 are reduced. And the engine is discriminated as it is at idling or driving by an engine speed detecting circuit, feeding the control circuit 8 with an electric signal, whereby a three-way valve is operated, and at the time of idling, a negative pressure port 25 is interconnected to a suction pipe but at the time of driving, it is interconnected to a positive pressure part. Since a pressure differential between empty spaces 35 and 36 dwindles away to nothing and it grows larger the other way at the time of idling and driving, the actuator 6 locks a movable mass body 9 and pushes up a pressing device 23, opening it.
