Abstract
A fluid filtering device, comprises: a housing having a fluid inlet and a fluid outlet for the fluid to be filtered, and a flushing outlet for the dirt separated from the fluid; a supporting core extending longitudinally within the housing; a plurality of annular filter discs supported as a stack on the supporting core; and a pressure plate supported at one end of the stack, and movable in one longitudinal direction to tighten the stack by pressing the discs together, or in the opposite direction to loosen the stack. A cleaning nozzle is supported within the housing for movement along the length of the stack and has its axis oriented to apply a flushing fluid eccentrically to the discs, when the stack is loosened, to rotate the disc on the supporting core and thereby to flush the dirt particles therefrom through the flushing outlet.

A fluid filtering device, comprising:
- a housing having a fluid inlet and a fluid outlet for the fluid to be filtered, and a flushing outlet for the dirt separated from the fluid;
- a supporting core extending longitudinally within said housing;
- a plurality of annular filter discs supported as a stack on said supporting core;
- a pressure plate supported at one end of said stack, and movable in one longitudinal direction to tighten the stack by pressing the discs together, or in the opposite direction to loosen the stack;
- and a cleaning nozzle supported within the housing for movement along the length of the stack and having its axis oriented to apply a flushing fluid eccentrically to the discs, when the stack is loosened, to rotate the disc on the supporting core and thereby to flush the dirt particles therefrom through the flushing outlet.

- a supporting core extending longitudinally within said housing;
- a plurality of annular filter discs supported as a stack on said supporting core;
- a pressure plate supported at one end of said stack, and movable in one longitudinal direction to tighten the stack by pressing the discs together, or in the opposite direction to loosen the stack, said pressure plate being slidably carried at one end of said supporting core and being coupled to a handle externally of the housing by a threaded member which is rotated by said handle to move the pressure plate to its stack-tightening position or to its stack-loosening position;
- and a cleaning nozzle supported within the housing for movement along the length of the stack and having its axis oriented to apply a flushing fluid eccentrically to the discs, when the stack is loosened, to rotate the disc on the supporting core and thereby to flush the dirt particles therefrom through the flushing outlet.
