Estimating the term…
A hydraulic system, especially in a high-pressure application, comprises a pressurized-fluid tank, a pressurized-fluid pump driven by a drive unit, at least one hydraulic load that can be pressurized thereby and a control and/or distribution unit connected fluidically between the pressurized-fluid pump and the load. This unit is provided with a housing and a core received therein and connected rigidly with the housing, which core bears with part of its surface in the region of a common, closed, especially cylindrical joint face with the housing on a corresponding inside face of a housing opening. Surface groove-like flow ducts are provided on the core and/or the housing in the region of the joint face, and the pressurized-fluid pump is directly built onto the control and/or distribution unit in the region of a free end face of the core.
A hydraulic system for a high-pressure application, comprising a pressurized-fluid tank (1, 1″), a pressurized-fluid pump (4, 4″) driven by a drive unit, at least one hydraulic load pressurized thereby and a control and/or distribution unit (5, 5″) connected fluidically between the pressurized-fluid pump and the load, which control and/or distribution unit (5, 5″) is provided with a housing (6, 6′, 6″) and a core (7, 7″) received therein and connected rigidly with the housing, which core bears with part of its surface (12) in the region of a common, closed, cylindrical joint face with the housing on a corresponding inside face (13) of a housing opening (8, 8″), surface groove-like flow ducts (14, 15, 16, 17, 18) being provided on the core and/or the housing in the region of the joint face, and the pressurized-fluid pump being directly built onto the control and/or distribution unit in the region of a free first end face (23) of the core.
