Patent ID: 8870992

Claim:
A hydraulic filter for precipitating solid particles from a medium comprising: a filter housing, including a filter head closing the filter housing at an end, the filter head defining an inlet channel and an outlet channel; and a filter element disposed within said filter housing, wherein a direction of flow of the medium is provided from an outer surface to an interior of the filter element, said interior being connected to the outlet channel, wherein the outer surface, together with the filter housing, delimits an inlet chamber connected to the inlet channel, wherein the inlet channel and the inlet chamber are designed in such a way that a centrifugal force acting approximately in a direction toward the filter housing acts on the medium flowing into the inlet chamber and on the solid particles, wherein the inlet channel has an oblique channel section extending obliquely to the longitudinal axis of the filter and opening approximately between the filter element and the filter housing, wherein the inlet channel has a radial channel section adjacent to the oblique channel section, wherein the radial channel section extends radially with respect to a longitudinal axis of the filter and is connected to an inlet port, and wherein the inlet channel has a longitudinal channel section adjacent the oblique channel section extending approximately parallel to the longitudinal axis of the filter and opening into the filter housing.
