摘要:
An electromagnetic valve (1) includes: a solenoid coil (10); a valve body (20) configured to be driven by electromagnetic force of the solenoid coil (10); a coil bobbin (30) including a cylindrical portion (32) and a pair of flanges (34) disposed so as to extend radially outward from opposite ends of the cylindrical portion (32), and holding the solenoid coil (10) in a space formed between the pair of flanges (34) at an outer circumferential side of the cylindrical portion (32); a valve casing (40) including a shaft portion (42) inserted through the cylindrical portion (32) of the coil bobbin (30), and accommodating the coil bobbin (30) disposed around the shaft portion (42), the solenoid coil (10) and the valve body (20); and a filler (2) disposed in a gap, if any, between an inner circumferential surface (33) of the cylindrical portion (32) of the coil bobbin (30) and an outer circumferential surface (43) of the shaft portion (42) of the valve casing (40). The filler (2) has a higher thermal conductivity than air.
摘要:
An oil tank (28) is disposed in a nacelle (7) supported on a tower (14) of a wind turbine generator (100), for storing oil used in an oil using unit (4) included in the wind turbine generator (100). The oil tank (28) at least includes: a first oil chamber (48) and a second oil chamber (50) for storing the oil; a partition wall (52) which separates the first oil chamber (48) and the second oil chamber (50); and an oil heater (56) for heating the oil in the oil tank. The partition wall (52) includes at least two openings (54a, 54b) through which the first oil chamber (48) is in communication with the second oil chamber (50) so that the oil is movable between the first oil chamber (48) and the second oil chamber (50).
