摘要： The invention relates to a metering device comprising
a housing (12) having a metering opening (22), controllable by the movement of an axially moveable valve needle, an axially extendable piezoelectric actuator (28) cooperating with the valve needle to control its axial movement, and a thermal compensator unit (30) to compensate for different thermal expansion of the housing (12) and the piezoelectric actuator (28). According to the invention the thermal compensator unit (30) comprises a compensator housing (32) and a hydraulic piston (34), disposed axially slidable within the compensator housing (32), the compensator housing (32) and the piston (34) forming a first fluid chamber (36), a second fluid chamber (38) and a throttling passage (40) connecting the first (36) and second fluid chamber (38), and means for transmitting an axial extension of the piezoelectric actuator (28) to the compensator housing (32) or to the piston (34) to urge a hydraulic fluid from the first fluid chamber (36) to the second fluid chamber (38) in an activation phase of the piezoelectric actuator (28).摘要翻译： 本发明涉及一种计量装置，其包括具有计量开口（22）的壳体（12），其可通过可轴向移动的阀针的运动控制;可轴向延伸的压电致动器（28），其与阀针配合以控制其轴向运动 ，以及用于补偿壳体（12）和压电致动器（28）的不同热膨胀的热补偿器单元（30）。 根据本发明，热补偿器单元（30）包括补偿器壳体（32）和液压活塞（34），其可在补偿器壳体（32）内轴向滑动地设置，补偿器壳体（32）和活塞（34）形成 第一流体室（36），第二流体室（38）和连接第一流体室（38）的节流通道（40）和用于传递压电致动器（28）的轴向延伸的装置， 在所述压电致动器（28）的激活阶段中，将补偿器壳体（32）或所述活塞（34）推压到所述第一流体室（36）到所述第二流体室（38）。

摘要： The invention concerns a thermal compensator unit that allows to precisely set and keep an equilibrium position. Further, the fluid chambers (4, 5) respectively comprise at least one elastic element (7, 8) so that the respective volume is variable, which elastic elements (7, 8) hermetically seal the fluid chambers, which leads to the effect that no plastic or rubber dynamic sealing is necessary between the sliding parts in a hydraulic compensator, in particular since the moving parts (1) of the hydraulic compensator are preferably hermetically connected to said respective elastic element (7) and/or build a part thereof.

摘要： The invention concerns a thermal compensator unit that allows to precisely set and keep an equilibrium position by providing an adjustable pre-compression on one of two fluid chambers (4, 5). Further, the fluid chambers (4, 5) respectively comprise at least one elastic element (7, 8) so that the respective volume is variable, which elastic elements (7, 8) hermetically seal the fluid chambers, which leads to the effect that no plastic or rubber dynamic sealing is necessary between the sliding parts in a hydraulic compensator, in particular since the moving parts (1) of the hydraulic compensator are preferably hermetically connected to said respective elastic element (7) and/or build a part thereof.
