Abstract

PURPOSE:To make it possible to supply coolant from a main pump even after stopping of an engine, by coupling the drive shaft of the main pump with an output take-out mechanism through a one-way clutch, and as well by coupling an auxiliary electrical motor to the above-mentioned shaft through a one-way clutch. CONSTITUTION:An output shaft 19 constituting an output take-out mechanism 9 for a Sterling engine, and the drive shaft 17 of a main pump 11 are coupled together by means of a pulley 10 and an one-way clutch 21. Further, the above- mentioned drive shaft 17 is coupled with an auxiliary electrical motor 14 by means of a pulley 20 and an one-way clutch 21. Accordingly, when the above- mentioned output shaft 19 is rotated, the pulley 20 is not operated so that the torque of the output shaft 19 is alone transmitted to the main pump 11. Further, when the Sterling engine is stopped and the electrical motor 14 is driven, the torque of the motor 14 is transmitted to the main pump 11 through the pulley 20 and the one-way clutch 21 while the output shaft 19 is rested by means of the one-way clutch 19.

The main pump (11) is connected to the drive shaft of the main pump (11) through the QCII, and the main pump (11) is operated during the operation of the mechanism, and the auxiliary pump (13) arranged in the coolant circuit (12) is electrically operated after the Stirling engine is stopped. Drive 1 with the motor (14) to enable IJ function. The electric motor (14) operates after the engine is stopped, and while the sensor (15) detects the temperature of the cooling medium in the circuit, the control unit (16) determines whether the temperature of the cooling medium has fallen below a set value. However, when the temperature of the cold IJ medium falls below a set value, the electric motor (14) is stopped.

取付けは、容易でなく、組付は作業を難しくさせる。An example of the auxiliary pump (13) and electric motor (14) is disclosed in Japanese Patent Laid-Open No. 51-66952. No. 4 of the same bulletin
As is clear from the figure, the drive shaft of the auxiliary pump and the vane at its tip are arranged in the curved pipe section of the coolant circuit. Since the blades are perpendicular to the drive shaft, the cooling medium circuit always requires a curved pipe section to accommodate the blades. Therefore, the existence of the curved pipe portion and the blades of the auxiliary pump increases the flow resistance of the cooling medium when the main pump is driven. Furthermore, the attachment of the auxiliary pump is not easy, making assembly difficult.

ンジンに利用し易くなる。In the present invention, when the Stirling engine is in operation, its power take-off mechanism drives the main pump. At this time, the one-sided clutch on the electric motor side does not transmit the drive to the electric motor. When the Stirling engine stops, the electric motor is activated and drives the main pump. However, the driving force of the electric motor is not transmitted to the output extraction mechanism side by the one-sided clutch on the output extraction mechanism side. Thus, the main pump can supply cooling medium even after the engine has stopped. According to the invention, by the arrangement of the one-way clutch,
The main pump is activated after the engine is stopped, and the structure is simple, low cost, and easy to assemble. Furthermore, compared to the case where an auxiliary pump is used, there are fewer sealing parts and there is less risk of coolant leakage, making it easier to use in engines such as vehicles.
