Sealing cushion

A gasket installed on the inner peripheral surface of an opening of a housing such as a cylinder head cover and sealing the gap between the housing and an insertion member such as a plug tube inserted in the opening. The gasket has good installability, so that, even if the inner diameter of the opening is not made to high precision, an outer periphery installation section of the gasket is prevented from being nipped in fitting of the gasket into the housing, or the gasket can be reliably fitted into the housing. To achieve the above, the outer diameter of the outer periphery installation section is set equal to or less than the inner diameter of the opening, and a tightening allowance setting means and a radial direction positioning means are provided on an outer peripheral section of the outer periphery installation section of the gasket. The tightening allowance setting means sets a tightening allowance of the gasket relative to the inner peripheral surface of the opening, and the radial direction positioning means performs radial positioning of the gasket relative to the inner peripheral surface of the opening. The tightening allowance setting means is inclined in the axially opposite direction to the direction of fitting of the gasket into the housing and has a lip shape whose outer diameter in a free state is set greater than the inner diameter of the opening.

Cooling device

ActiveCN102109240AWith throttling functionMaintain cycle refrigerant quantityMechanical apparatusCompression machines with non-reversible cycleRefrigerantIntermediate pressure
The invention provides a cooling device, and thus in a cooling device with a critical pressure formed at a high-pressure side, the amount of a circulatory refrigerant in a refrigerant circuit can be properly maintained, and the overload operation of a compressing mechanism due to an abnormally high pressure can be prevented. The invention relates to a cooling device (R) with a supercritical pressure formed at the high-pressure side, and the device comprises: a refrigerant amount adjusting box (100) connected to the high-pressure side through a communicating circuit (101); a communicating circuit (103) communicating the upper part of the box and an intermediate-pressure region in the refrigerant circuit; a communicating circuit (105) communicating the lower part of the box and the intermediate-pressure region in the refrigerant circuit; an electric expansion valve (102) of the communicating circuit (101); a solenoid valve (104) of the communicating circuit (13); a solenoid valve (106) of the communicating circuit (105); and a control device (C) controlling the electric expansion valve (102) and various valve devices to recover the circulatory refrigerant in the refrigerant circuit into the box and to charge the refrigerant into the refrigerant circuit (1).

Refrigeration device

Provided is a refrigeration device which can, independently of outside air temperature, ensure stable refrigeration performance when the high-pressure side has a supercritical pressure, and which can improve cost and the easiness of construction. A refrigeration device is provided with: a pressure regulating throttle means which is connected to a refrigerant circuit which is located downstream of a gas cooler and upstream of a main throttle means; a decompression tank which is connected to a refrigerant circuit which is located downstream of the pressure regulating throttle means and upstream of the main throttle means; a split heat exchanger which is provided in a refrigerant circuit which is located downstream of the decompression tank and upstream of the main throttle means; an auxiliary circuit which allows a refrigerant within the decompression tank to be sucked into the intermediate pressure section of a compressor after causing the refrigerant to flow to a first flow passage in the split heat exchanger through an auxiliary throttle means; and a main circuit which allows a refrigerant to flow out from the lower part of the decompression tank, causes the refrigerant to flow to a second flow passage in the split heat exchanger, subjects the refrigerant to heat exchange with a refrigerant flowing through the first flow passage, and then causes the refrigerant, having been subjected to heat exchange with the refrigerant flowing through the first flow passage, to flow into the main throttle means.

Tape expansion device

The invention provides a tape expansion device. The tape expansion device comprises a frame maintaining unit, an expansion part, an expansion part work unit, a drive lode detection unit, a control unit and a display unit. The frame maintaining unit is provided with an annular maintaining surface used for maintaining an annular frame. The expansion part has the diameter less than the inner diameter of the annular frame and larger than the diameter of a chip, and acts on a cutting tape mounted on the annular frame on the annular maintaining surface of the frame maintaining unit, and makes the cutting tape expand. The expansion part work unit enables the expansion part to work in the direction perpendicular to the annular maintaining surface of the frame maintaining unit. The drive load detection unit detects the drive load of the expansion part work unit. The control unit determines whether the cutting tape is broken according to a detection signal output by the drive load detection unit. The display unit displays determine results of the control unit. Under a condition that the control unit makes the expansion part work unit works and expands the cutting tape, the control unit determines that the cutting tape is broken according to the detection signal output by the drive lode detection unit when the drive load decreases under a condition that the drive load increases as the cutting tape is expanded.
