摘要:
A metabolic syndrome relieving agent that is free from a problem of side effects and can be taken for a long term is provided. Bergamottin is used as an agent for relieving a metabolic syndrome. Since bergamottin has functions of activating PPARα and PPARγ, promoting the secretion of adiponectin in adipocytes and inhibiting the generation of VLDLs in hepatic cells, it is possible to prevent or treat diseases such as insulin resistance, hyperinsulinism, type 2 diabetes, obesity, visceral fat obesity, hypertension, hyperlipemia, arteriosclerosis and the like and thus prevent or treat the metabolic syndrome. Also, as understood from the fact that citrus fruits such as a grapefruit or the like containing bergamottin have been eaten for many years, they have no problems in terms of safety and have a low calorie content, and therefore, they can be taken for a long term. Further, since bergamottin is tasteless and odorless, it does not impair the unique taste of a food when added to this food, so that it can be added to foods and taken.

An expansion valve includes a valve body having a valve body hole, a first passage, a bottomed valve chamber, a second passage, a third passage and a guide member disposed in the valve body hole between the first passage and the third passage. The valve body hole has a first valve body hole portion and a second valve body hole portion of different diameters forming a valve body step between the second passage and the first passage. The guide has a first guide portion and a second guide portion of different diameters forming a guide portion step. The guide is sized to be slidably received by the valve body hole in a close-fitting relationship with the first valve body hole portion receiving the first guide portion, the second valve body hole portion receiving the second guide portion and the valve body step and the guide portion step contacting each other.

An expansion valve 1 includes a square rod-shaped valve body 10. A first path 20 into which refrigerant is introduced, a valve chamber 22 formed near the bottom of the path, a second path 24 for refrigerant heading toward an evaporator and a third path 26 for refrigerant returning from the evaporator are provided to the valve body 10. A valve member 30 provided inside the valve chamber is operated by a power element 70 via an actuating rod 60. In order to assemble the expansion valve, an assembled orifice member 40 and an assembled guide member 100 are press-fitted into an opening provided to the valve body 10.

A power element portion 36′ mounted on the upper portion of an expansion valve body comprises an upper cover 36d and a lower cover 36h, and is divided into an upper pressure chamber 36b and a lower pressure chamber 36c by a diaphragm 36a. A heat sensing drive shaft 101 is formed of a large radius portion 105 and a heat conducting shaft 103 integrally formed thereto. The stopper portion 104 contacting the lower surface of the diaphragm 36a is a member which is formed separately from the heat sensing drive shaft 101, and supported within the lower cover 36h. When the expansion valve is taken apart, the heat sensing drive shaft 101 is pulled out from the inside of the mounting seat 362 of the power element portion 36′, and the refrigerant remaining inside the upper pressure chamber 36b is taken out and collected from the side of the diaphragm.

An expansion valve comprises an orifice formed in a valve body and a valve member fixed to a movable member. Movement of a diaphragm is transmitted to an actuating rod via a member and the actuating rod actuated the movable member to control the opening amount of the path between the valve member and the orifice. An orifice member affixed to the orifice is made of a material harder than the valve body, and free from erosion or other damage by a refrigerant, which will otherwise occur at the valve opening portion.

A unit incorporating a reservoir tank and an expansion valve into a single built-in structure comprises a reservoir tank 10 sealed by a cover 20, and an expansion valve 30 fixed on the cover 20. A refrigerant pipe 40 extending through the cover 20 introduces a refrigerant from a compressor through a condenser into the reservoir tank 10. The refrigerant introduced into the expansion valve 30 through a pipe 50 increases in volume, and then enters an evaporator. After passing the evaporator, the refrigerant in the gaseous phase flows through pipe 62 into the expansion valve 30, then delivers thermal information of the refrigerant to a heat sensitive member of the expansion valve, and travels in a pipe 70 extending into and from the reservoir tank 10. While traveling along the pipe 70, the gaseous refrigerant exchanges heat with the liquid refrigerant stored in the reservoir tank, and then returns to the compressor.

The body of a valve has an orifice that internally connects a high-pressure passage through which a refrigerant flows in and a low-pressure passage through which the refrigerant flows out. The valve includes a valve plug for adjusting the flow rate of the refrigerant flowing in the orifice, an operating rod for moving the valve plug in a valve opening direction, and a temperature sensing drive unit for driving the operating rod. A support ring for constraining the spherical valve plug is located on the upper-stream side of the high-pressure passage with respect to the orifice. The support ring is formed of a circular annular portion capable of elastic deformation and vibration-proof springs. The springs support the valve plug.

An expansion valve 1 comprises a piping member 10 equipped with passages to which refrigerant pipes are connected, and a cassette unit 100, the two members being formed as separate units. The cassette unit 100 comprises a tube member 110 having a flange portion 111, and at the interior of the tube member 110 are fixed a guide member 170, an orifice member 180, and a plate member 166. The pressure of the gas filled in a gas charge chamber 122 defined by a lid 120 and a diaphragm 130 displaces the diaphragm 130, the displacement being transmitted through a stopper member 140 to a shaft member 150. The shaft member 150 is guided by a guide member 170 and controls the valve means 160 inside a valve chamber 161. The cassette unit 100 is inserted to the piping member 10 and fixed to position by a ring 50. Seal members 62, 64, and 66 are equipped to appropriate areas between the cassette unit and the piping member.
