    • Provided is a variable-capacity compressor control valve where a valve body can be easily machined and the machining time and machining cost can be reduced without a decrease in the valve closing property or a decrease in the slidability of the valve element due to shaft misalignment. The valve body includes a support member having formed therein a valve orifice and a guide hole into which the valve element is adapted to be slidably fitted and inserted; and a body member having formed therein a Ps inlet/outlet port, a Pd introduction port, and a Pc inlet/outlet port. The support member is fixedly inserted into a recess hole provided in the body member. In addition, a chip sealing portion (pocket portion) for sealing chips of the body member and/or the support member is provided between the body member and the support member.
    • 本发明提供一种容量可变的压缩机控制阀,其能够容易地对阀体进行机械加工,并且可以在不降低阀闭合性能的情况下减少加工时间和机械加工成本,或者可以降低由于轴偏移引起的阀芯的滑动性。 所述阀体包括支撑构件,所述支撑构件中形成有阀孔和引导孔,所述阀芯适于可滑动地装配和插入所述引导孔中; 以及形成有Ps入口/出口,Pd导入口和Pc入口/出口的主体构件。 支撑构件固定地插入设置在主体构件中的凹入孔中。 另外,用于密封主体部件和/或支撑部件的芯片的芯片密封部分(袋部分)设置在主体部件和支撑部件之间。

    • The invention relates to a machining tool for machining bores, comprising a main part (3) which has a central axis (5) in a circumferential surface (7), at least two geometrically defined cutting edges (9/1 to 9/5) which are unevenly distributed on the circumferential surface (7) of the machining tool (1) when seen in the circumferential direction of the machining tool (1), and a number of guide strips which project from the circumferential surface (7) of the main part (3). The machining tool (1) is characterized in that two guide strips (19/1, 19/2) are designed to be stationary and are arranged with a circumferential spacing of less than 180° relative to one another such that a first circumferential region (21/1) is formed which lies between the stationary guide strips and extends over more than 180°, and a second circumferential region (21/2) is formed which extends over less than 180°; such that one (9/1, 9/2) of the at least two cutting edges (9/1 to 9/5) is arranged in the second circumferential region (21/2) between the stationary guide strips (19/1, 19/2); and such that at least one guide strip (23) is spring-mounted on the main part (3), and the at least one spring-mounted guide strip (23) is arranged in the first circumferential region (21/1) such that the at least one spring-mounted guide strip (23) resiliently presses the machining tool (1) against the stationary guide strips (19/1, 19/2) when machining a bore.
    • 本发明涉及一种用于加工孔的加工工具,其包括在圆周表面(7)中具有中心轴线(5)的主要部分(3),至少两个几何限定的切削刃(9/1至9/5) 在沿着加工工具(1)的圆周方向观察时,不均匀地分布在加工工具(1)的圆周面(7)上,并且从主体的圆周面(7)突出的多个导向条 第(3)部分。 所述加工工具(1)的特征在于,两个引导条(19/1,19/2)被设计为固定的并且相对于彼此以小于180°的周向间隔布置,使得第一周向区域 21/1)形成在固定引导条之间并且延伸超过180°,并且形成延伸超过180°的第二周向区域(21/2); 使得所述至少两个切削刃(9/1至9/5)中的一个(9/1,9/2)布置在所述固定导向条(19/1, 19/2); 并且使得至少一个引导条(23)弹簧安装在主要部分(3)上,并且至少一个弹簧安装的引导条(23)布置在第一周向区域(21/1)中,使得 当加工孔时,所述至少一个弹簧安装的引导条(23)将加工工具(1)弹性地压靠固定导向条(19/1,19/2)。
