Filtering unit and relative filtering cartridge
Abstract:
A filtering unit (10) comprising a casing (20) provided with at least one inlet (32), one outlet (33) and one support body (42) provided with abutment surfaces (44) adapted to removably support a filtering cartridge (50) contained within the casing (20) and adapted to divide the internal volume of the casing (20) into two chambers (21,22) respectively connected with the inlet (32) and the outlet (33) so as to filter the fluid flowing from the inlet (32) towards the outlet (33), the filtering cartridge (50) comprising at least one coupling element (55) configured to be snap-coupled to the support body (42) following a first axial translation for mutual approaching between the filtering cartridge (50) and the support body (42), whose distinctive characteristic lies in the fact that it comprises cam means (57,58) operating between the coupling element (55) and the support body (42) so as to radially bend the coupling element (55) in a release position for disengaging the coupling element (55) from the support element (42) following a further limited mutual axial translation between the filtering cartridge (50) and the support body (42), moving in the same direction with respect to the first approaching translation, the cam means (57,58) being configured so as to keep the coupling element (55) in release position following a slight mutual rotation between the filtering cartridge (50) and the support body (42).
Abstract(Chinese):

一种过滤单元（10），包括设置有至少一个入口（32），一个出口（33）和一个支撑体（42）的壳体（20），所述壳体设置有抵靠表面（44），所述邻接表面适于可移除地支撑过滤筒 ）包含在壳体（20）内并且适于将壳体（20）的内部容积分成分别与入口（32）和出口（33）连接的两个室（21,22），以便过滤流体流动 从入口（32）朝向出口（33），过滤筒（50）包括至少一个联接元件（55），其被配置成在第一轴向平移之后被卡扣联接到支撑体（42），以相互接近 过滤筒（50）和支撑体（42），其特征在于其包括在联接元件（55）和支撑体（42）之间操作的凸轮装置（57,58），从而径向地 将联接元件（55）弯曲在释放位置以使联接元件脱离 （50）和所述支撑体（42）之间的另一有限的相互轴向平移之后，相对于所述第一接近平移沿同一方向移动，所述凸轮装置（55）从所述支撑元件（42） ，58）被构造成使得所述联接元件（55）保持在所述过滤筒（50）和所述支撑体（42）之间的轻微相互旋转之后处于释放位置。
