    摘要： Disclosed is a valve in which a small driving force of a drive source is required when the valve is closed. A valve includes a valve housing and a valve body to be driven by a drive source, and controls a flow rate of a fluid flowing through a through-flow passage in a direction opposite a closing direction of the valve body, by moving the valve body from a control region to a closing region. The valve body has an effective pressure-receiving area where a pressure of the fluid acts on the valve body. The effective pressure-receiving area is switched between the effective pressure-receiving area in the control region and the effective pressure-receiving area in the closing region. The effective pressure-receiving area is smaller than the effective pressure-receiving area Rs1.

    摘要： A displacement control system (A) of a variable displacement compressor comprises a target pressure setting means (402A) setting a target for pressure in an intake chamber or a crank chamber, on the basis of evaporator-outlet air temperature detected by an evaporator-outlet air temperature detection means (510) and a target for evaporator-outlet air temperature set by an evaporator-outlet target air temperature setting means (512), a discharge pressure detection means (500) detecting the pressure of a refrigerant in a high-pressure section, and a current regulation means (404, 406) regulating current supplied to a solenoid (316) of a displacement control valve, on the basis of the pressure of the refrigerant in the high-pressure section detected by the discharge pressure detection means (500) and the target for pressure set by the target pressure setting means (402A).

    摘要： A variable capacity air conditioner compressor is controlled by setting a car target indoor temperature; sensing car indoor and outdoor temperatures and solar radiation with sensors at predetermined car positions; calculating a vent target discharge temperature using the target temperature, sensed car temperatures and solar radiation; calculating a target evaporator temperature and blower voltage based on target discharge temperature; calculating a control duty based on the target evaporator temperature; calculating target evaporator temperature and blower voltage change rates; determining whether or not the compressor conies under a sudden variable condition based on the control duty, and target evaporator temperature and blower voltage change rates; and setting a control duty change rate maximum value to an accelerative slew rate greater than and equal to a basic slew rate when sudden and not sudden variable conditions are respectively determined.
