Claims

[Scope of utility model registration request]

The interior is divided into two rooms by the compartment 6, and
a lower case 2 having inlets 7 and 9 for each chamber;
A main flow path and a bypass flow path are formed with the upper case 1 having an outlet 29, and in the main flow path,
A felt filter assembly 3 having a felt filter 12 is also provided in the bypass flow path.
Bypass valve assemblies 4 each having a wire mesh filter 17 and a bypass valve 18 are provided,
When the bypass valve 18 is not operated due to the suction negative pressure at the outlet 29, oil flows to the inlet 7.
When the bypass valve 18 is actuated by the suction negative pressure, oil flows in from the inlet 9 and passes through the wire mesh. A fluid filter device for an automatic transmission, characterized in that fluid is filtered by a filter 17 and flows out from an outlet 29.
