摘要： An expansion valve includes: a body (2) having a second passage (14) through which a refrigerant returning from an evaporator passes, and a mounting hole (50) communicating with the second passage (14); a power element (3) mounted on the body (2) in such a manner as to close the mounting hole (50); a shaft (33) that transmits a drive force from the power element (3) to a valve element (18); and a plate (31) that separates an open space (S2) from the second passage (14), has an insertion hole (36), through which the shaft (33) extends, coaxially along a central axis of the plate (31), and limits a flow of the refrigerant from the second passage (14) into the open space (S2) to a flow through a clearance between the shaft (33) and the insertion hole (36). The insertion hole (36) is formed such that an opening area of the clearance between the shaft (33) and the insertion hole (36) is 7.0 mm 2 or smaller.

摘要： A control valve (1, 201, 301) includes: a first valve (7) to control a flow rate of refrigerant flowing from a discharge chamber to a control chamber of a compressor; a second valve (8) to control a flow rate of the refrigerant flowing from the control chamber to a suction chamber; a solenoid (3, 203, 303) to generate a drive force in a first valve (7) closing direction and a second valve (8) opening direction depending on supplied current; a biasing member (42, 242) to generate a biasing force in a first valve (7) opening direction and a second valve (8) closing direction; and a pressure sensing part (6) to sense a pressure (Ps, PC) in the suction chamber or the control chamber, and generate a counterforce against the drive force depending on the sensed pressure. A state in which both of the first and second valves (7, 8) are open is present during a process in which the amount of current supplied to the solenoid (3, 203, 303) is increased from zero to an upper limit current value, and an increase rate of an opening degree of the first valve (7) is increased during a process in which the amount of current supplied to the solenoid (3, 203, 303) is decreased, a predetermined lower limit current value being an inflection point of the increase.

摘要： A motor device includes a stator core (26), and a positioning structure that positions the stator core (26). The stator core (26) is constituted by multiple core members (30) arranged around a rotor (14) in circumferential directions. The core members (30) each have multiple teeth parts (36) of which the front end surfaces radially face the rotor (14). The positioning structure includes multiple positioner parts (44) that respectively abut against the multiple core members (30) to position the multiple core members (30). The multiple positioner parts (44) include first positioner parts (44-A) that each abut against a front end part of a teeth part (36) of each of core members (30) adjacent to each other in the circumferential directions.
