摘要:
Two oil passages are defined in a cylinder unit of a rotary compressor for feeding lubrication oil to front and rear bearings. The bearings bear a shaft of a rotor unit relative to the cylinder unit. At least one of the two oil passages is formed with an orifice which is defined by the cylinder unit.

A damper door controller is provided for remotely controlling damper doors of a cooler/heater unit of an automotive air conditioner. The controller comprises a knob holder (3); at least one rotary knob (4,5,6) rotatably connected to the knob holder (3); a pinion (14) coaxially connected to the rotary knob (4) to rotate therewith; an elongate guide slot (17) formed in the knob holder (3); a rack member (18) slidably received in the guide slot (17), the rack member (18) being operatively meshed with the pinion (14); a cable assembly (21) including a control cable and a sleeve in which the control cable slides, the control cable having a leading end fixed to a leading end of the rack member; and a clamp member (23) provided by the knob holder and extending across a generally middle portion of the guide slot to clamp a leading end of the sleeve.

A brushless motor comprises a parts protecting case; a drive shaft rotatable about its axis relative to the parts protecting case; a fixed housing for rotatably holding therein the drive shaft; a stator tightly held by the fixed housing; a shock absorbing unit interposed between the fixed housing and the parts protecting case to suppress transmission of vibration of the fixed housing to the parts protecting case; a yoke connected to the drive shaft to rotate therewith; and a plurality of magnets held by the yoke. The yoke has a vibration damping structure to suppress or at least minimize transmission of vibration of the yoke to the drive shaft.

A tank of heat exchanger (100) comprises a tank body (102) and a pipe member (106). The tank body (108) is made of clad metal and shaped like a channel member with a base wall (102c) and two opposed side walls (102a,b). The pipe member (106) is first spot welded with its flance (110) to the tank body (102) and then finally brazed in a furnace.

The height of a bead opposing a joint where side edges of a plate are to be joined is set to be smaller than the height of a bead which does not oppose the joint by the thickness of the plate. Further, lands are provided between the beads and protrude from either the tube surface or the tube surface toward the inside of the main tube unit, and flow gaps are formed through which the heat-exchange medium flows over the lands.

A stack type evaporator (1,100) for use in an automotive air conditioner comprises generally a first mass (111) which includes first heat exchanging elements (117), each first heat exchanging element having mutually independent first (120) and second (121) passages; and a second mass (112) which includes second heat exchanging elements (118), each second heat exchanging element having a generally U-shaped third passage (122) which has first and second ends. The second mass is arranged beside the first mass in such a manner that the first and second heat exchanging elements are aligned on a common axis. An inlet tank passage (114) connects to upper ends of the first passages. An upstream tank passage connects to lower ends of the first passages and the first ends of the third passages. A downstream tank passage connects to lower ends of the second passages and the second ends of the third passages. An outlet tank passage (115) connects to upper ends of the second passages. An inlet pipe (103) connects to the inlet tank passage. An outlet pipe (104) is connected to the outlet tank passage.
摘要:
A structure for mounting an oil cooler (213) to a heat-exchanger tank (211) is disclosed. A long-scale oil cooler (213) is received in a heat-exchanger tank (211), and pipe portions (217,219) are formed only on one side of the oil cooler so that the pipe portions are inserted respectively in pipe holes (211a,211b) formed in the tank (211). A support portion (227) for supporting the other side of the oil cooler (213) where no pipe portion is formed is formed on an inner surface of the tank (211). Further, a laminate type oil cooler (213) is provided. The oil cooler (213) has a core portion (31) in which a plurality of shells (21) each having an oil flow path (27) formed therein are laminated. A first oil passage hole (33) is formed at a first side end of the core portion, and a second oil passage hole (35) is formed at a second side end of the core portion (31). The laminated shells (21) are made to communicate with each other by the first and second oil passage holes. Further, a third oil passage hole (37) is formed between the first oil passage hole (33) and the second oil passage hole (35) in a width direction of the core portion (31). Only a part of all laminated shells in a lamination direction of the shells are made to communicate with each other by the third oil passage hole (37). Further, a blocking member (51) is disposed in the oil flow path of the shell having the third oil passage hole (37) so as to block oil flow, the blocking member (51) being disposed between the third oil passage hole (37) and the first oil passage hole (33).
