  • Compressor
    Patent number: 7320578
    Abstract: A compressor includes a housing for accommodating a compression mechanism, and an oil separator including a cylindrical body having inner and outer cylinders defining therebetween an annular oil separating chamber and fixed in a communication passage of the housing. The outer cylinder is spaced from a communication passage-forming portion of the housing to define a gap therebetween, extends along a slit formed in the communication passage-forming portion of the housing, and is formed with an opening directed tangential to the oil separating chamber and facing part of the slit. Gas discharged from the compression mechanism flows through the slit and the opening into the oil separating chamber to form a swirl flow, so that lubricating oil is centrifugally separated from the gas. Part of the gas collies with an outer face of the outer cylinder, whereby lubricating oil is separated from the gas.

  • Clutchless variable displacement refrigerant compressor with mechanism for reducing displacement work at increased driven speed during non-operation of refrigerating system including the compressor
    Patent number: 7320576
    Abstract: In a variable displacement swash plate type refrigerant compressor (10), a stopper (28) is provided for setting an initial angle of the inclination angle of a swash plate (23) when a drive shaft (19) is not driven. When the drive shaft (19) is driven by a driving power source of the compressor (10) under a non-operation condition of a refrigerant circuit, the stopper (28) is moved to permit the inclination angle of the swash plate (23) to be reduced from the initial angle in response to increase of compression work of the compressor (10) so as to suppress the increase of the compression work to save the driving power for the compressor (10).

  • Ice shaver for beverage dispenser
    Patent number: 7287713
    Abstract: An ice shaver for a beverage dispenser for charging solid granular ice into cups and shaving granular ice and charging it into cups. An ice charging port opening arranged to expose the part of one end surface of the impeller in the direction of the impeller central axis including the spindle allows granular ice to be charged into the ice shaver body while being agitated by the impeller ameliorate clogging of the bottom end side of the introduction pipe. Also, because the impeller is rotated at a low speed in discharging granular ice, the discharge speed of the ice is reduced, reducing scattering of beverage already in the cup. Furthermore, when an overload occurs in a motor due to the impeller locking caused by clogging with granular ice, driving of the impeller is stopped. Therefore, the motor and a motor drive section are protected from damage due to over current and heating.

  • Power transmission device
    Patent number: 7270606
    Abstract: A power transmission device prevents vibration in a rotation direction and collision noise, even if a shock absorbing rubber is permanently deformed in a compression direction. Specifically, even if compression forces repeatedly applied to a shock absorbing rubber causes the shock absorbing rubber to be permanently deformed in a compression direction, an elastic member placed between the shock absorbing rubber and each protrusion presses circumferentially the shock absorbing rubber of a pulley and a transmission ring, and therefore, a shock of an abrupt rotation number change caused by rattling between the shock absorbing rubber and the transmission ring may be absorbed by the elastic member, and vibration in a rotation direction and collision noise may be prevented.
