Description

【特許請求の範囲】
【請求項1】 内部空間を囲むリング状横断面を有する交換可能なフィルタ要素と、フィルタ交換時にフィルタを空にする排出導管と、上記内部空間内に延びる中央排出ドーム体とを備える液体フィルタにして、上記内部空間に浄化液体用排出口が接続し、そして排出ドーム体がフィルタ要素とともに、上記排出導管を閉じる第1の閉止位置と上記排出導管を開放する第2の開放位置との間で軸方向可動に装着されており、
上記排出ドーム体(9)がフィルタケーシングに固設され、ばね作用を受けて上記開放位置へ押しやられており、そしてフィルタケーシング(2)内にフィルタ要素(4)を挿入することによりばね作用に抗して上記閉止位置へ可動であり、
上記排出ドーム体(9)がまたフィルタ迂回弁(11)をも構成するか、またはフィルタ迂回弁(11)と結合されている、液体フィルタ。
【請求項2】 上記排出口(7)が側方で排出ドーム体(9)に接続し、軸方向で排出導管(15)に接続する、請求項1に記載の液体フィルタ。
【請求項3】 上記排出ドーム体(9)がまた逆止め弁(24)をも構成するか、または逆止め弁(24)と結合されている、請求項1に記載の液体フィルタ。
【請求項4】 上記弁(11)が、軸方向に可動な排出ドーム体(9)の位置により、開放状態と閉止状態の間で可動である、請求項1に記載の液体フィルタ。
【請求項5】 上記弁(11)が、排出ドーム体(9)から独立して設けられたパッキン面(23、27)と協動する弁体(22、25)を有する、請求項1に記載の液体フィルタ。
【請求項6】 排出ドーム体(9)が、フィルタ要素(4)用支持ドーム体(5)を形成して、内部空間(6)内に延びている、請求項1に記載の液体フィルタ。
【請求項7】 排出ドーム体(9)が、排出ドーム体(9)の軸方向に前後して配置された2つの部分より構成される、請求項6に記載の液体フィルタ。
【請求項8】 フィルタ要素(4)が、別個のパッキン構成部材を要することなく、排出ドーム体(9)に直接接続する、請求項1に記載の液体フィルタ。
【請求項9】 内部空間(6)内に設けられ、浄化液体用の上部流入開口部および上記出口(7)に接続する下部流出開口部を備えた分離管(29)が、更に備えられ、当該分離管(29)が上記出口(7)の壁に緊密に接続して、液密なシールを形成し、浄化液体または未浄化液体の流入を阻止する、請求項1に記載の液体フィルタ。
[Claims]
1. A liquid filter including a replaceable filter element having a ring-shaped cross section surrounding an internal space, a discharge conduit that empties the filter when the filter is replaced, and a central discharge dome body extending into the internal space. The purifying liquid discharge port is connected to the internal space, and the discharge dome body together with the filter element is between the first closed position for closing the discharge conduit and the second open position for opening the discharge conduit. It is mounted so that it can move in the axial direction.
The discharge dome body (9) is fixed to the filter casing, is pushed to the open position by the spring action, and is spring-loaded by inserting the filter element (4) into the filter casing (2). It is movable to the above closed position against it,
A liquid filter in which the discharge dome body (9) also constitutes a filter bypass valve (11) or is coupled to a filter bypass valve (11).
2. The liquid filter according to claim 1, wherein the discharge port (7) is laterally connected to the discharge dome body (9) and is axially connected to the discharge conduit (15).
3. The liquid filter according to claim 1, wherein the discharge dome body (9) also constitutes a check valve (24) or is coupled to the check valve (24).
4. The liquid filter according to claim 1, wherein the valve (11) is movable between an open state and a closed state depending on the position of the discharge dome body (9) which is movable in the axial direction.
5. The first aspect of the invention, wherein the valve (11) has a valve body (22, 25) that cooperates with a packing surface (23, 27) provided independently of the discharge dome body (9). The liquid filter described.
6. The liquid filter according to claim 1, wherein the discharge dome body (9) forms a support dome body (5) for the filter element (4) and extends into the internal space (6).
7. The liquid filter according to claim 6, wherein the discharge dome body (9) is composed of two portions arranged back and forth in the axial direction of the discharge dome body (9).
8. The liquid filter of claim 1, wherein the filter element (4) is directly connected to the discharge dome body (9) without the need for a separate packing component.
9. A separation tube (29) provided in the interior space (6) and provided with an upper inflow opening for purifying liquid and a lower outflow opening connected to the outlet (7) is further provided. The liquid filter according to claim 1, wherein the separation pipe (29) is tightly connected to the wall of the outlet (7) to form a liquid-tight seal and prevent the inflow of purified liquid or unpurified liquid.
