摘要:
Compressor has a driving unit. The driving unit is provided within a crank chamber and decreases the discharge capacity when a control valve opens a control passage to increase the pressure within the crank chamber. The throttle passage delivers oil with the compressed refrigerant to the crank chamber regardless of whether the control valve has opened or closed the control passage. Because the throttle passage may continuously deliver the oil to the crank chamber even when the control valve closes the control passage, the mechanical elements within the crank chamber can be reliably and sufficiently lubricated and the crank chamber is prevented from being in an insufficiently lubricated state.

A control valve is located in a variable displacement compressor incorporated in a refrigerant circuit. The control valve controls the displacement of the compressor in accordance with a pressure difference between a first pressure monitoring point and a second pressure monitoring point, which are located in the refrigerant circuit, such that the pressure difference seeks a predetermined target value. An adjusting valve, which is a variable throttle valve, is located in a section of the refrigerant circuit between the first and second pressure monitoring points. The adjusting valve adjusts the restriction amount of the refrigerant in relation to the refrigerant flow in the refrigerant circuit. The compressor displacement is thus optimally controlled.

Variable displacement compressors (101) include a displacement control valve (181) that is in communication with a drive chamber (111). The output displacement of the compressor varies in response to changes in pressure within the drive chamber. A controller (203) may control the displacement control valve so that the pressure within the drive chamber is maintained within a predetermined range. Further, the predetermined range may be determined based upon one or more factors that cause fluctuations in the pressure within the drive chamber during operation of the compressor.

A displacement control mechanism used in a variable displacement compressor for controlling a displacement of the compressor includes a first control valve located on a supply passage and a second control valve located on a first bleed passage. The second control valve includes a backpressure chamber having substantially the same pressure atmosphere as a region of the supply passage downstream of the first control valve and a spool including a back surface that is located in the backpressure chamber. The spool reduces an opening degree of the first bleed passage when a pressure in the backpressure chamber is increased. The spool blocks a communication between the backpressure chamber and the first bleed passage via a clearance formed around a cylindrical outer peripheral surface of the spool in the second control valve when the spool sets the first bleed passage at a minimum opening degree.

A compressor is provided in which the arrangement and the position of a spring chamber, in which a coil spring biasing a main shaft is accommodated, are designed and the various designs of the compressor is possible. The compressor comprises a main shaft (16), a front housing (11) which has a shaft aperture that rotatably supports the front side of the main shaft, a cylinder block (12) in which a shaft aperture is located on the rear side of the front housing and rotatably supports the rear side of the main shaft and in which cylinders are disposed on the outer circumferential side of the shaft aperture, a rear housing (13) which has a suction chamber and a discharge chamber that are disposed on the rear side of the cylinder block and can communicate with the inside of the cylinders, and a coil spring (32) which biases the main shaft from a rear side to a front side, wherein the rear housing includes a recess (13c) or a seat portion which defines at least a part of a spring chamber that accommodates the coil spring.

A display processing apparatus includes a first display controller that displays a background image in a display unit; and a second display controller that displays a print image in the display unit. The second display controller changes a magnification of the print image so that the print image has a size obtained by changing a size of a recording medium on which the print image is to be printed on a scale of the background image displayed in the display unit, and superimposes and displays the print image on the background image.

A display processing apparatus includes a transparent display data generating unit and a preview image generating unit. Based on document data including color plane image data indicating an area for which use of a color developer is specified and transparent plane image data indicating an area for which use of a transparent developer is specified together with the type of transparent processing performed on the area by using the transparent developer, the transparent display data generating unit generates pieces of transparent display data showing a result of image formation corresponding to the transparent processing with the transparent developer for each type of transparent processing. The preview image generating unit generates a preview image by projecting a color display plane on which the color plane image data is displayed and transparent display planes on which the pieces of transparent display data are displayed in a three-dimensional space onto a two-dimensional plane.
