Embodiment Construction

[0024] figure 1 Shows a cross-sectional side view of a first embodiment of a container 1 according to the invention for a hydraulic circuit, in particular a hydraulic oil compensation tank of a hydraulic power steering according to the invention in a first operating position. The container 1 comprises a substantially cylindrical shell 2 with a longitudinal axis 3 . Housing 2 has figure 1 Inlet 4 is shown as well as in the figure 1 Outlet not shown in , inlet 4 is used for hydraulic fluid (more specifically, hydraulic oil) from connection to container 1 but in figure 1 The hydraulic circuit, also not shown in further detail, is received into the container 1, more specifically, hydraulic fluid is received from the hydraulic circuit of the hydraulic power steering device into the container 1, and the outlet is used to discharge the hydraulic fluid to the container 1 hydraulic circuit.

[0025] From figure 1 As seen in more detail in , the container 1 comprises at least one f...

Abstract

A reservoir for a hydraulic system includes a housing having an inlet and an outlet. The inlet is adapted to receive an incoming fluid and is formed within an inlet tube that extends into the housing. A filter within the housing, includes a filter element, defining an inner filter chamber, and includes an inlet opening encompassing the inlet tube that extends into the housing. The inlet opening allows the incoming fluid to enter the inner filter chamber for filtration. A base wall around the inlet opening includes a guide step that guides a relative movement between the reservoir and the filter. A relative movement between the filter and the reservoir facilitates the base wall, the guide step, and the inlet tube, to co-operate and establish a bypass route for selectively allowing the incoming fluid to bypass the filter, depending upon a predetermined differential pressure between the inlet and the outlet.

Description

technical field [0001] According to the claims, the invention relates to a container for a hydraulic circuit, more particularly to a hydraulic oil compensation tank of a hydraulic power steering device. Background technique [0002] In hydraulic circuits such as power steering for motor vehicles, it is essential for trouble-free and long-life operation that the hydraulic fluid, such as hydraulic oil, flowing through the circuit be kept free of solid components, such as Suspended particulate matter. For this purpose, known filters are used to ensure a certain quality of the hydraulic fluid. It is generally desirable to provide a filter with the smallest possible mesh width in order to be able to filter even the smallest particulate matter from the fluid flow. This type of filter is also called a fine filter. However, this can cause problems at low operating temperatures of the hydraulic circuit, for example during the initial stages of operation, since the viscosity of the...
