  • Patent number: 11001936
    Abstract: A rotational surface treating device with a high treatment efficiency that allows a treatment liquid to be discharged in a short time is provided. When a treatment bath 2 is rotated, parts 20 contact an electrode 50 to be electroplated. In this event, a plating liquid 16 is used as circulated by a pump P. The plating liquid 16 is discharged to the outside through a gap in a side wall 80 for replacement of the plating liquid 16 or the like. During discharge, the plating liquid 16 is not circulated by the pump P. The gap 8 which is formed in the side wall 80 is formed to be smaller than the minimum dimension of the parts 20 on the inner side. The gap 8 is formed to be wider toward the outer side. Thus, water is discharged immediately.

  • Patent number: 10981475
    Abstract: A seat air-conditioning system includes a plurality of seat air-conditioning devices respectively disposed for seats. Each of the seat air-conditioning devices achieves comfortable air conditioning in a vehicle interior by a controller controlling a refrigeration circuit, a blower, and a blowing switching portion in each seat air-conditioning device. A coordinating flow path is disposed to fluidly connect the blowing switching portion of one seat air-conditioning device to the blowing switching portion of the other seat air-conditioning device. The seat air-conditioning system performs the air conditioning for one seat by using the two seat air-conditioning devices by supplying conditioned air via the coordinating flow path under control of the controller.

  • Publication number: 20190383308
    Abstract: When an ejector having a variable nozzle and a variable throttle mechanism are integrated together as an ejector module, a nozzle-side central axis CL1 and a decompression-side driving mechanism have a twisted positional relationship, if the nozzle-side central axis CL1 is defined as a central axis of a nozzle-side driving mechanism in a displacement direction in which the nozzle-side driving mechanism of the ejector having the variable nozzle displaces a needle valve, and the decompression-side central axis CL2 is defined as a central axis of a decompression-side driving mechanism in a displacement direction in which the decompression-side driving mechanism of the variable throttle mechanism displaces a throttle valve. When viewed from the central axis direction of one of the nozzle-side central axis CL1 and the decompression-side central axis CL2, a driving portion corresponding to the one central axis is disposed to overlap with the other central axis.

    Abstract: A refrigeration cycle device includes a compressor, a first branch portion, a radiator, a second branch portion, a first decompressor, a first evaporator, a second decompressor, a second evaporator, and an ejector. The first branch portion divides a flow of a refrigerant discharged from the compressor into one flow and an other flow. The radiator radiates heat of the refrigerant of the one flow. The second branch portion divides a flow of the refrigerant from the radiator into one flow and an other flow. The first decompressor decompresses the refrigerant of the one flow divided in the second branch portion. The second decompressor decompresses the refrigerant of the other flow divided in the second branch portion. A nozzle of the ejector decompresses and injects the refrigerant of the other flow divided in the first branch portion. The refrigerant suction port draws the refrigerant from the second evaporator.

  • Publication number: 20190107124
    Abstract: An ejector includes a shaft coupled to a passage formation member defining a refrigerant passage inside a body, and the shaft is slidably supported by a support member fixed to the body. A drive mechanism moves the shaft in an axial direction to change a passage sectional area of the refrigerant passage. The passage formation member is provided with a vibration suppressive member including a first mobile end that applies a load to enlarge the refrigerant passage and a second mobile end that applies a load to narrow the refrigerant passage. Both the first mobile end and the second mobile end are disposed on a same side of a slide region of the support member in the axial direction.

  • Patent number: 9726407
    Abstract: A temperature sensitive rod is communicated with a diaphragm that is displaceable in response to a pressure difference between an internal pressure of a sealed space, in which a temperature sensitive medium is sealed, and a pressure of a low pressure refrigerant outputted from an evaporator. A blind hole, which opens to the sealed space, is formed in an inside of the temperature sensitive rod. The temperature sensitive medium is a mixture gas of the refrigerant and an inert gas. A mixing ratio of the inert gas in the temperature sensitive medium corresponds to a ratio of an equivalent diameter of the blind hole relative to a depth of the blind hole in such a manner that a time constant of heat conduction from the temperature sensitive rod to the temperature sensitive medium is kept within a desired time constant range.

  • Patent number: 9683761
    Abstract: In an integration valve, a body, in which a vapor-liquid separating space is provided, includes a fixed throttle decompressing liquid-phase refrigerant, a liquid-phase refrigerant side valve body member opening or closing a liquid-phase refrigerant passage, and a vapor-phase refrigerant side valve body member opening or closing a vapor-phase refrigerant passage. Further, the vapor-phase refrigerant side valve body member is configured by a differential pressure regulating valve operated based on a pressure difference between a refrigerant pressure at a side of the vapor-phase refrigerant passage and a refrigerant pressure at a side of the liquid-phase refrigerant passage. The vapor-phase refrigerant side valve body member is movable when the liquid-phase refrigerant side valve body member is moved by a solenoid. Therefore, a cycle configuration of a heat pump cycle configuring a gas injection cycle can be simplified.

  • Patent number: 9636622
    Abstract: An accumulator has a tank and a desiccant. The tank separates refrigerant flowing to the tank into vapor-phase refrigerant and liquid-phase refrigerant, therein stores the liquid-phase refrigerant, and emits the vapor-phase refrigerant toward a suction side of a compressor. The desiccant is disposed in the tank and removing a water content from the refrigerant. Liquid-phase refrigerant included in the refrigerant flowing to the tank drops downward from a location that is located above the desiccant, and is stored in a lower portion in the tank. Vapor-phase refrigerant included in the refrigerant flowing to the tank is drawn through a suction port that is located above the desiccant to flow out of the tank. At least a part of the desiccant is exposed to vapor-phase refrigerant under a normal condition, and the desiccant is located at a location that is away from a dropping route of liquid-phase refrigerant in the tank.

  • Patent number: 9541316
    Abstract: An accumulator is disposed in a refrigerant circuit at a position on the suction side of a compressor, separates the gas and liquid phases of the refrigerant, and contains the liquid refrigerant. The accumulator comprises: a pressure container (2) having an inner space (S) formed therein; a refrigerant inlet opening (5) provided in the pressure container; a refrigerant outlet opening (6); a conduction pipe (8) for conducting a refrigerant within the pressure container to the outlet opening; and a gas-liquid separation means (15) provided with a separation plate (16) provided within the pressure container so as to face the inlet opening and so as to expand substantially perpendicularly to the direction of the line of flow at the inlet opening. The gas-liquid separation means has, in the region of the separation plate which faces the inlet opening, a mountain-shaped protrusion (18) having a crest (18a) and a sloped surface (18b), the crest (18a) protruding toward the inlet opening.

  • Publication number: 20160290525
    Abstract: In a first expansion valve, a pair of fitting side surfaces, which are formed in a screw member, is opposed to a pair of groove side surfaces, respectively, which are formed in a rotatable member. The fitting side surfaces are rotated about an axis by the groove side surfaces. An overlapping width, throughout which the groove side surface and the fitting side surface are overlapped with each other, is larger than a female-thread inner diameter of a threaded hole, into which the screw member is threadably engaged.
