    • An inner cylinder (10), a pin (21), and a valve body (26) are movable in a reciprocating manner in a direction along the rotational axis in relation to an oil supply pipe (24). At a proximate position, where a cutter attaching portion (11) is close to the oil supply pipe, a rod portion (27) of the valve body is supported by a pressure receiving portion of the holder inner cylinder (10) due to the elastic force of a compression coil spring (29), such that an opening-closing portion (28)of the valve body closes a valve port (25) of the oil supply pipe. At a separated position, where the cutter attaching portion is separated from the oil supply pipe, the rod portion of the valve body is supported by the upper end of the pin (21) due to the elastic force of the compression coil spring, instead of the pressure receiving portion, such that the opening-closing portion opens the valve port.
    • 内筒(10),销(21)和阀体(26)能够相对于供油管(24)沿着旋转轴线的方向往复运动。 在切割器安装部分11靠近供油管的邻近位置处,由于弹性件,阀体的杆部分(27)由保持器内筒(10)的受压部分支撑 压缩螺旋弹簧(29)的力,使得阀体的打开 - 关闭部分(28)关闭供油管的阀口(25)。 在切割器安装部分与供油管分离的分离位置处,阀体的杆部由于压缩螺旋弹簧的弹力而被销(21)的上端支撑,而不是 压力接收部分,使得打开 - 关闭部分打开阀口。

    • The invention relates to a transmission oil circuit with an oil pump for conveying oil or another medium from an oil sump or associated media sump, comprising: a heat exchanger through which the oil flows in order to remove heat from the oil; with a working pressure valve, against which the oil pump conveys the oil in order to bring the conveyed oil to a predetermined working pressure for pressure actuating, pressure oil application or pressure oil supply of switching valves and/or other transmission components and/or other aggregates outside of the transmission that are arranged in the flow direction upstream from the working pressure valve in a row thereto or in the flow direction downstream from a supply line that branches upstream from the working pressure valve in the transmission oil circuit. The invention is characterized in that the heat exchanger can be switched in a first position upstream or in a second position downstream from the working pressure valve in an alternating manner regarding the sequence of the flow with oil originating from the oil pump, or the heat exchanger can be switched in a first position upstream or in a second position downstream from the switching valves, other transmission components and/or other aggregates or with an arrangement in or downstream from the branched supply line, upstream or downstream from the branching point regarding the sequence of the flow with oil originating from the oil pump in an alternating manner.
