摘要： A variable displacement pump includes: a first control oil chamber which moves a cam ring toward a direction against a biasing force of a biasing member when a discharge pressure is introduced thereinto; a second control oil chamber which acts a hydraulic pressure upon the cam ring by cooperating with the biasing force of the biasing member when hydraulic oil is introduced thereinto; a switching mechanism which switches between one state in which hydraulic oil whose pressure is decreased than a discharge pressure is introduced to the second control oil chamber from the discharge section and another state in which hydraulic oil is discharged from the second control oil chamber; and a control mechanism operated before an eccentricity of the cam ring becomes a minimum and which discharges a greater amount of hydraulic oil within the second control oil chamber as the discharge pressure becomes larger.

摘要： Variable displacement compressor is provided with a displacement control valve (2) that can change an opening degree of supplying passage (44, 46) between a valve seat (VS) and a valve body (VB), thereby changing the pressure in a crank chamber (9). The displacement control valve (2) is accommodated within a control valve chamber (5c) in a rear housing (5) and fixed in place by means of a circlip (50). A cutout (50g) is formed between the displacement control valve (2) and the circlip (50) and/or between the circlip (50) and the rear housing (5). A clearance (C) formed by the cutout (50g) and the like inhibits the transmission of vibrations caused by impacts between the valve seat (VS) and the valve body (VB). This makes the variable displacement compressor quiet, reduces costs by obviating the need for additional components, and results in excellent durability.

摘要： A hollow rack shaft is manufactured through a first step, a second step and a third step. At the first step, the plate-like workpiece of substantial rectangular shape is press formed into a gutter-like shape. The first die set used at this step is provided with slant die surfaces for canceling elastic recovering generated at the workpiece when the workpiece is removed from the first die set. At the second step, a row of rack teeth is press-formed on the flat bottom portion of the workpiece formed in the first step. The die set used at the second step is provided with a recess for releasing surplus workpiece material within the die clearance at a stroke end of the pressworking. At the third step, each of a pair of legs of the workpiece is bent in a semi-circular shape so as to be butted to each other. At this time, a mandrel is inserted between the legs of the workpiece.

摘要： To accurately detect a trouble of a magnetic brake (2) by eliminating any effect of a temperature of a location at which an elevator is installed, a temperature sensor (3) is arranged to measure a temperature of the magnetic brake (2). When an armature (2c) has been attracted responsive to a brake release command, the temperature of the magnetic brake is measured as a first temperature, and before the armature returns responsive to a brake actuation command, the temperature of the magnetic brake is measured as a second temperature. The first and second temperatures are compared with each other. When a result of the comparison between the first and second temperatures is determined to be greater than a predetermined value, the magnetic brake (2) is determined to have been locked and hence, to have developed a trouble.

摘要： A hollow rack shaft is produced by forming a plate work piece and has continuous metal flow along the contour of rack teeth surface without being cut. A series of wave-like concave-convex sections is formed on the inner surface of the shaft. Thickness of tooth body and tooth bottom of the rack teeth is adjusted by dimensions of the unevenness. Thereby, stress concentration at each point of the rack shaft is prevented and the shaft is strengthened and its weight reduced.
