A method enhances fatigue strength of ear portions which are high fatigue risk parts in a torsion beam almost without bringing about disadvantages in terms of productivity and cost. A torsion beam is formed with a portion of the tubular body into an approximately U-shape in cross section by crushing the portion of the tubular body in the radial direction and, thereafter, due to bending with a bottom line set as a belly side of bending, a bending strain of 2 to 6% in the tube longitudinal direction on a tensile side is imparted to the ear portions.

In a structure for mounting a filter in a compressor, a mounting member is connected to the filter. A receiving hole is formed in a housing of the compressor for receiving therein the mounting member. A first fitting portion is formed on an inner circumferential surface of a holding portion of the filter. A second fitting portion is formed on an outer circumferential surface of the mounting member for having fitting relation to the first fitting portion for an overlap distance in a radial direction of the receiving hole. When the mounting member is received in the receiving hole with the fitting relation, the filter is disposed in a fluid passage of the housing. A clearance having a dimension is formed between an outer circumferential surface of the holding portion and an inner circumferential surface of the receiving hole. Minimum value of the dimension is smaller than the overlap distance.

A displacement control valve () is connected to a variable displacement compressor. An open passage () in which a refrigerant gas flows is formed within a rod () and a valve body () of the displacement control valve (). Further, an inner circumferential surface of a valve chamber () is formed as a guide portion () for moving the valve body () along an axis (L) of the valve chamber (). A valve portion () of the valve body () is formed in a circular arc cross sectional shape along a surface of a sphere (K) in which an intermediate point of a length of the guide portion () along the axis (L) of the valve chamber () is set to a center (N) on the axis (L), and a distance from the center (N) to a contact point between a valve seat () and the valve portion () is set to a radius (r).

A displacing device is incorporated in a displacement control valve. The displacing device includes a first pressure chamber, a second pressure chamber, a second bellows, a transmission rod, and an urging spring. The second pressure chamber communicates with a suction chamber. The interior of the second pressure chamber is a suction pressure zone. When the pressure in the suction pressure zone is less than or equal to a predetermined reference pressure, the transmission rod moves an actuation rod (valve body) to open a valve hole. Therefore, a variable displacement compressor is prevented from operating with a large displacement when there is insufficient amount of refrigerant or when the speed of the compressor is high.

Displacement control mechanism for variable displacement compressor

In a control system of a variable displacement compressor, a pressure sensing means mechanically detects at least one pressure in the refrigerant circuit. A varying means varies a reference value for positioning a valve body. A pressure detector electrically detects the pressure detected by the pressure sensing means in the refrigerant circuit and/or physical quantity which correlates with the detected pressure. A calculator calculates a maximum value of urging force applied to the valve body by the varying means toward an increasing side of the displacement of the compressor. The urging force applied to the valve body is controlled not to exceed the maximum value toward the increasing side of the displacement. The displacement of the compressor is maximized by the pressure sensing means under the pressure for calculating the maximum value when the varying means applies urging force of the maximum value to the valve body.

A welded steel pipe is formed by heating or soaking an untreated welded steel pipe having a steel composition containing, on the basis of mass percent: about 0.03% to about 0.2% C, about 2.0% or less of Si, not less than about 1.0% to about 1.5% Mn, about 0.1% or less of P, about 0.01% or less of S, about 1.0% or less of Cr, about 0.1% or less of Al, about 0.1% or less of Nb, about 0.1% or less of Ti, about 0.1% or less of V, and about 0.01% or less of N; and by reduction-rolling the treated steel pipe at a cumulative reduction rate of at least about 35% and a final rolling temperature of about 500&deg; C. to about 900&deg; C. The welded steel pipe exhibits excellent hydroformability, i.e., has a tensile strength of at least about 590 MPa and an n&times;r product of at least about 0.22. The treated steel pipe is preferably reduction-rolled at a cumulative reduction rate of at least about 20% below the Ar transformation point.

A control valve has a valve body for opening and closing a valve hole and a solenoid mechanism for urging the valve body by energizing a solenoid. The solenoid mechanism includes a yoke, a plunger housing, a fixed core and a plunger. The yoke accommodates the solenoid and forms a magnetic path. The plunger housing made of stainless steel connects with the yoke, and has a central axis. The fixed core connects with the yoke. The plunger is accommodated in the plunger housing and connects with the valve body. The plunger is attracted to the fixed core to move in the direction of the central axis by applying electromagnetic force from the solenoid. Black oxide treatment is performed to the yoke after the plunger housing is brazed to the yoke.

A first bleed passage and a second bleed passage each connect a crank chamber of a compressor with a suction chamber of the compressor. A first supply passage and a second supply passage each connect the crank chamber with a discharge chamber of the compressor. A first control valve adjusts the opening size of the first supply passage in response to the pressure in the suction chamber. A second control valve includes a ball valve and an electromagnetic actuator. The ball valve adjusts the opening size of the second supply passage and the opening size of the first bleed passage. The electromagnetic actuator moves the ball valve. The ball valve is moved to a first position and to a second position. At the first position, the ball valve closes the second supply passage and opens the first bleed passage. At the second position, the ball valve opens the second supply passage and closes the first bleed passage. A displacement control device, which includes the first and second control valves, readily and reliably changes the displacement of the compressor.
