Title:
CYLINDRICAL FILTER ELEMENT AND HIGH PRESSURE FLUID JOINT MEMBER HAVING THE SAME
Document Type and Number:
WIPO Patent Application WO/2009/093338
Kind Code:
A1
Abstract:
In a cylindrical filter element (1), a cylindrical reinforcing part (7) whose
tip is blocked by a blocking part and in which a plurality of through holes are opened
on a peripheral face is protrusively arranged on one opening side of a circular
base part (3) having a fluid hole (2), and a cylindrical filter part (4) is engaged
with an outer periphery of the cylindrical reinforcing part (7) so as to fix them.
In a high pressure fluid joint member (16), a cylindrical filter element storing
part (23) storing the cylindrical filter element (1) is arranged in a fluid path
(17). The cylindrical filter element storing part (23) has a circular base part
storing room (26) having an inner peripheral face (24) in a confronted position
with an outer peripheral face of the circular base part (3) of the cylindrical
filter element (1). A seal ring (29) is installed between the outer peripheral
face of the circular base part (3) of the cylindrical filter element (1) and the
inner peripheral face (24) of the circular base part storing room (26). A communicating
part (30) communicating the fluid hole (2) and the circular base part storing
room (26) is formed in the circular base part (3) of the cylindrical filter element
(1). Thus, the cylindrical filter element (1) which can prevent deformation
of the cylindrical filter part (4) by fluid pressure and can securely match axes
of the circular base part (3) and the cylindrical filter part (4), and the high
pressure fluid joint member (16) which can effectively function the seal ring
(29) can be obtained.
