阅读说明：本技术 恒温阀芯 (Thermostatic valve core ) 是由 阿克塞尔·贝莱尔 马修·德瑞伯 于 2020-04-07 设计创作，主要内容包括：该阀芯(1)包括基部(10)、用于调节冷流体和热流体的混合物的温度的恒温调节系统(20、30)、以及用于调节混合物的流速的系统,该系统包括固定部(60)和可移动部(61)。固定部设置有用于冷流体和热流体的吸入通道(63F、63C)和返回通道(64F、64C),并且被固定地装配在基部上,使得返回通道分别通向基部的入口(16、17)。可移动部以可移动的方式装配到固定部,使得沿着基部的轴线(X-X),可移动部的第一面轴向接合抵靠固定部的第二面,从而形成接合界面(62)。可移动部设置有非贯通连接通道,该非贯通连接通道分别用于冷流体和热流体,且根据可移动部的位置能够建立吸入通道与返回通道的连通。为了使阀芯在接合界面处较少经受泄漏的风险,该阀芯针对冷流体和热流体中的每一者包括隔室(70、71),该隔室布置在可移动部的第二面上并通过可移动部与接合界面连通,以便被供应来自对应的吸入通道的流体,而与可移动部的位置无关。(The cartridge (1) comprises a base (10), a thermostatic regulation system (20, 30) for regulating the temperature of a mixture of cold and hot fluids, and a system for regulating the flow rate of the mixture, the system comprising a fixed part (60) and a movable part (61). The fixed part is provided with suction channels (63F, 63C) and return channels (64F, 64C) for cold and hot fluid and is fixedly fitted on the base part so that the return channels open into the inlets (16, 17) of the base part, respectively. The movable part is movably fitted to the fixed part such that, along an axis (X-X) of the base part, a first face of the movable part axially engages against a second face of the fixed part, forming an engagement interface (62). The movable part is provided with non-through connection channels for cold and hot fluid, respectively, and which enable to establish a communication of the suction channel with the return channel depending on the position of the movable part. In order to make the valve spool less subject to the risk of leakage at the joint interface, it comprises, for each of the cold and hot fluids, a compartment (70, 71) arranged on the second face of the movable portion and communicating with the joint interface through the movable portion, so as to be supplied with fluid from the corresponding suction channel, independently of the position of the movable portion.)
