摘要： PROBLEM TO BE SOLVED: To provide an air conditioning device for a vehicle for reducing uncomfortable feeling of an occupant due to the temperature rise in a cabin even when an engine turns to a highly loaded state. SOLUTION: If an operation state detection means 2 detects that the state enters upward slope travel, starting acceleration or middle acceleration travel with an opening degree of an accelerator, while an air conditioning state detection means 1 stably detects comfortable steady air conditioning state, a power saving operation mode determination means 3 determines that the state enters power saving operation mode. In the power saving operation mode, a refrigeration capacity control means 4 reduces the refrigeration capacity, and lightens the load of the engine. It improves the traveling performance of a vehicle, and a blowing-out direction control means 5 controls a blowing-out direction varying device 6 to change the blowing-out direction so as to directly apply an air conditioned wind to the occupant. Even if the temperature in the cabin rises due to lowering of the refrigeration capacity, it reduces the uncomfortable feeling by the occupant. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a capacity control valve for a variable capacity compressor of a flow control type without necessity of a large solenoid force. SOLUTION: A first control valve 30A disposed at a discharge side refrigerant channel of the compressor, and having a function of a variable orifice which can freely set a channel sectional area in response to the solenoid force of a solenoid 30C; and a second control valve 30B for controlling a flow rate of a refrigerant of a discharge pressure PdH to be introduced to a crank chamber of a pressure Pc, so that a differential pressure between a discharge pressure PdH of an upstream side of the valve 30A and a discharge pressure PdL of a downstream side becomes a predetermined value; are integrally constituted. Thus, a small-sized low cost capacity control valve for the variable capacity compressor can be realized. Since the solenoid 30C controls the valve 30A so as to generate a small differential pressure, the solenoid 30C may have a small solenoid force, and can be thus reduced in size.

摘要： PROBLEM TO BE SOLVED: To provide an expansion valve of constant flow rate not affected by the leakage of a refrigerant in a sliding part of a piston. SOLUTION: A piston 32 fixed to a shaft 25 of a solenoid is mounted on the way of a refrigerant passage where the refrigerant introduced to an refrigerant inlet 2 flows to a refrigerant outlet 3 through a main valve composed of a main valve seat 4 and a main valve element 5. The piston 32 has the outer shape having a clearance of a specific channel cross-section with respect to an inner wall of the refrigerant passage. When the refrigerant of more than the specific flow rate flows to the clearance, the pressure difference generated before and after thereof acts in the closing direction of a pilot valve, whereby the flow rate is reduced to keep a constant flow rate. The piston driving the main valve is mounted slidably between the refrigerant inlet 2 and a pressure chamber 9, and the refrigerant leaked through the sliding part is joined to the refrigerant introduced to the pressure chamber 9 through an orifice 8, and controlled by the pilot valve, whereby the leakage of the refrigerant has no influence on the sliding part.

摘要： PROBLEM TO BE SOLVED: To provide a capacity control valve for a shortening time in transferring operating capacity.
SOLUTION: This capacity control valve comprises a valve element 21 for introducing a refrigerant of delivery pressure Pd in a delivery chamber to a pressure control chamber at pressure Pc1 and a valve element 22 for introducing a refrigerant of pressure Pc2 in the pressure control chamber to an intake chamber of suction pressure Ps, which are mutually interlockingly allowed to communicate and blocked; and a solenoid part for giving a solenoid force corresponding to a prescribed differential pressure to the valve elements 21 and 22. In a control for minimizing the operating capacity, the valve element 21 is fully opened, and the valve element 22 is fully closed; and in a control for maximizing the operating capacity, the valve element 21 is fully closed and the valve element 22 is fully opened, whereby the time in the transfer of operating capacity is shortened. The valve element 21 is formed integrally to a pressure sensitive central shaft 25, and the valve element 22 is allowed to abut on the central shaft, so that the difference in pressure receiving area between the valve elements 21 and 22 and the central shaft 25 is minimized to minimize the pressure receiving area applied to the valve elements 21 and 22, whereby the solenoid force for controlling the valve elements 21 and 22 is minimized.
