Title:
流体フィルタ及びそのドレン機構、流体フィルタに使用されるドレン用冶具並びに流体フィルタのドレン方法
Document Type and Number:
Japanese Patent JP4190383
Kind Code:
B2
Abstract:
A drain structure (7) for a fluid filter includes a cap (3) internally forming a drain hole (15). The cap (3) receives a valve member (21) urged by an urging means (11) in a direction, in which the valve member (21) blocks the drain hole (15). Normally, the drain hole (15) is blocked with a drain member (20). When fluid is drained from the drain hole (15), the drain member (20) is removed from the drain hole (15), and a drain tool (30) is inserted into the drain hole (15), so that the drain tool (30) displaces the valve member (21) in a direction, in which the drain hole (15) is unblocked. The drain tool (30) has a hooking portion (32) that can hook to a hooked portion (18) provided to the cap (3) by axially rotating the drain tool (30) inserted into the drain hole (15) of the cap (3). Thus, the drain tool (30) can be connected with the cap (3) while the hooking portion (32) is supported by the hooked portion (18).
