Abstract: A device for providing a signal warning of a clogging of a dust filter. A pair of air flow speed sensors A and B are arranged downstream of two sections of a dust filter 1 arranged in an air duct 1, and the outputs of the sensors A and B are connected to a comparator 6 having an output connected to a warning device 7. An obstacle 3 is arranged upstream or downstream of one section of the filter 1. When the filter is new, the speed of the air flow detected by the sensor B without an obstacle is higher than that detected by the sensor A located downstream of the obstacle, but the speed of clogging at the section without an obstacle is much higher than that at the section located downstream of the obstacle, and thus, after continuous use, the air speed detected by the sensor B becomes equal to that detected by the sensor A. The values of the detected speeds are compared to determine a degree of clogging of the filter, and to issue a warning signal when needed.

Abstract: A centrifugal type separator is disposed on a downstream side of a temperature-operating type expansion valve. Liquid-phase refrigerant separated herein is again pressure-reduced by an aperture resistance and thereafter inducted to an inlet side of the evaporator by means of a liquid-phase refrigerant discharge passage. Meanwhile, gas-phase refrigerant separated by the separator is returned directly from a gas-phase refrigerant discharge passage to an evaporator outlet side passage, and after being united with superheated gas-phase refrigerant evaporated by the evaporator, is taken into a compressor. A temperature-sensing tube of the expansion valve is disposed further on the downstream side of the foregoing union location so as to enable the temperature of the superheated gas-phase refrigerant evaporated by the evaporator to be sensed accurately.

Abstract: According to the present invention, a thermal expansion valve for a refrigerating cycle includes a housing having a throttle passage therein for expanding the refrigerant thereinto from the high-pressure side liquid refrigerant circuit, a valve element provided within the housing for adjusting opening degree of the throttle passage, and a thermosensitive element movably disposed within the housing. The thermosensitive element includes a case and a pressure responding member disposed within the case and displacing according to temperature and pressure of the refrigerant at the exit of an evaporator. The case of the thermosensitive element is integrally connected to the valve element, and the thermosensitive element and the valve element are so constructed as to integrally move according to the displacement of the pressure responding member. Accordingly, even if the valve element vibrates due to the sharp expansion of the refrigerant and the vibration transmits to the thermosensitive element case, as the thermosensitive element case is movable with respect to the housing and the housing are separated from the thermosensitive case, most of the vibration is prevented from being transmitted to the housing.

Abstract: An oil separator used in a refrigerating system. The oil separator comprises a body for forming a centrifugal oil separating chamber and an oil storage chamber, with a separating plate dividing the chambers. An inlet passage is connected tangentially to the oil separating chamber, to cause a swirl in the chamber, and a medium outlet passage extends inwardly from an end wall into the oil separating chamber. An oil outlet passage(s) is provided in the separating plate at a position near a periphery thereof. The oil separator body is formed integrally with the compressor housing and a ring member is fitted in an inner surface of the oil storage chamber, and a helically shaped narrow groove is provided on the outer surface thereof to form an oil returning passage. Also, the oil outlet passage can be provided in the separating plate at a position lower than a highest level of the oil storage chamber, thereby allowing the chambers to be arranged in a horizontal side by side relationship.
