Abstract: A variable displacement swash plate type compressor control method and a variable displacement swash plate type compressor controlled thereby may include a first determination step of determining whether liquid refrigerant exists within the variable displacement swash plate type compressor; a first operation step of applying power to the field coil assembly and of not applying current to the electronic control valve, when it is determined in the first determination step S1 that the liquid refrigerant exists; a second determination step of comparing an elapsed period of time of operating in the first operation step with a predetermined reference time; and a second operation step of maintaining the power applied in the first operation step to the field coil assembly and applying current to the electronic control valve when the elapsed period of time is greater than or equal to the reference time.

Abstract: Disclosed is a suction damping case. A refrigerant introduced into the suction damping case flows for a predetermined period of time at reduced pressure and speed, and then is discharged to the outside of the body, so that a damping function can be made. When the suction damping case is coupled to a rear housing, a hook and an embossing prevents the suction damping case from being separated.

Abstract: Disclosed is a field coil assembly of an electromagnetic clutch including a bobbin from which lead wires, which are both ends of a coil made of an aluminum-based material, protrude outward, a core that surrounds the bobbin such that the lead wires are exposed, a bobbin terminal installed at the bobbin while being adjacent to the lead wire of the coil, and a connector coupled to the core and including a lead wire terminal. The lead wires of the coil are connected to the bobbin terminal through heating and pressing.

Abstract: The present invention relates to a power transmission device for a water pump, including a pulley, a magnetic flux generator, a disk assembly, and a hub assembly, wherein the disk assembly has a disk, a friction ring for providing a frictional contact with the hub assembly, and a resilient ring adapted to pressurize the friction ring toward the hub assembly, so that when the attracting magnetic flux of the magnetic flux generator is not applied, the friction ring makes a frictional contact with the hub assembly through the resilient pressurization of the resilient ring, whereas, when it is applied, the disk moves toward the pulley to allow the frictional contact between the friction ring and the hub assembly to be released.

Abstract: The present invention relates to a field coil assembly of an electromagnetic clutch for a compressor. The present invention comprises a core 210, and a coil 240 installed to the core 210 and formed by winding a unit wire 250. At this time, the unit wire 250 wound on the coil 240 is made of aluminum, and an area ratio R of an inner sectional area M of the core 210 to a cross-sectional area of the unit wire 250 is 400 to 640. According to the present invention as above, since the unit wire 250 used for the coil 240 is made of aluminum with a small specific weight and low price rather than copper, the weight of the field coil assembly 200 is decreased to improve fuel efficiency of a vehicle and decrease a production cost of the field coil assembly 200.
