Abstract: A high pressure fluid filter provided with a pressure responsive member adapted to remain in unchanged position as long as the pressure acting on both sides of the pressure responsive member is balanced but which, upon an unbalance on either side of the pressure responsive member due to a contaminated filter element, is caused to move towards the side where the pressure is less and to thereby mechanically actuate a visual indicator device to signal the particular condition of the filter element and to further provide a bypassing arrangement to bypass the filter element upon an extremely contaminated condition of the filter element.

Abstract: In a case structure for a fluid pressure device, a filter that constitutes part of a fluid pressure unit is equipped with a first body, a case unit connected to a lower portion of the first body, and a filter unit accommodated in the interior of the case unit. The case unit is made up from an outer case, which is formed as a bottomed cylinder from a light-permeable transparent material, and an inner case inserted into the interior of the outer case. Additionally, by insertion of the case unit into an installation hole that opens on a lower portion of the first body and rotating the case unit, projections and retaining walls provided on an outer circumferential surface of the case unit engage with support members provided in the installation hole, thus placing the case unit in a connected state.
