Abstract
A filtration filter comprises a metallic mesh having a circumferential shape and radially inner and outer portions. The metallic mesh is adapted to filter out a filtration target object contained in a fluid passing through the membrane. First and second frame members hold the outer portion there between so as to create first and second bent sections separated by a transition section extending between the first and second bent sections. The transition section includes at least one streaked projection.
Claims9
A filtration filter, comprising:
- a metallic mesh having first and second opposed principle surfaces and a circumference, the metallic mesh having radially inner and outer portions;
- and
- a housing holding the metallic mesh and defining a fluid incoming path which opposes the first principal surface of the metallic mesh and a fluid discharging path which opposes the second principal surface, the housing including:
- a first housing section defining the fluid incoming path and including a first frame member;
- and
- a second housing section defining the fluid discharge path and including a second frame member;
- and
- the first and second housing sections forming a gap, the outer portion of the metallic mesh extending through at least a portion of the gap.
A filtration filter, comprising:
- a metallic mesh filter having a circumference and radially inner and outer portions;
- first and second frame members which cooperate to hold the outer portion of the metallic mesh filter in a recess defined by the first and second frame members, the recess including a conical section having an outer periphery;
- and
- a groove in the second frame member located radially outward of the conical section.
