Abstract: The invention relates to a thermostatic valve or the like of the type in which a spindle having a valve closure element at one end thereof is acted upon in one direction by a pressure responsive element and is biased in the other direction by a spring. The spindle is provided with screw threads and the spring which is conically shaped, has a coil portion complementary to and threadably engageable with the screw threads. The tension of the spring is adjusted by rotation of the spindle with a screwdriver or wrench depending on the type of tool engaging fitting the spindle is provided with at the lower end thereof.
Abstract translation: 本发明涉及一种恒温阀等，其中具有其一端的阀闭合元件的主轴通过压力响应元件在一个方向上作用，并且通过弹簧在另一个方向上偏置。 主轴设置有螺纹，并且具有锥形的弹簧具有与螺纹互补并与螺纹螺纹接合的线圈部分。 弹簧的张力通过使用螺丝刀或扳手的主轴的旋转来调节，这取决于主轴在其下端设置的工具接合配件的类型。
