Solution Overview
Problem
Existing gas separation devices in supply systems require large installation spaces and their separation efficiency deteriorates at higher flow velocities, failing to reliably separate gases under varying conditions.
Innovation Solution
A gas separation device with an arc-shaped separation section that utilizes centrifugal forces to pre-separate gaseous and liquid components before they enter a main chamber, combined with a closure mechanism to prevent fluid flow when a critical gas amount is detected, allowing compact design and efficient separation across different flow velocities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large housing is used for gas separation, then gas separation reliability is improved, but installation space requirement increases
Solution Approach 1:
The arc-shaped separation section performs preliminary gas-liquid separation before the fluid enters the main chamber. This pre-separation action reduces the amount of gas that needs to be handled in the main chamber, allowing for a more compact overall design while maintaining separation reliability.
Solution Approach 2:
The patent employs an arc-shaped separation section with specific curvature radius (R1 between 0.03m to 0.08m) to generate centrifugal forces that enhance gas-liquid separation. The curved geometry creates efficient separation without requiring a large housing volume, resolving the contradiction between compact size and separation effectiveness.
2Productivity
If flow velocity in the supply system increases, then temperature-controlled medium demand is met, but gas separation efficiency deteriorates
Solution Approach 1:
The patent optimizes the arc-shaped separation section parameters (curvature radius R1 between 0.03m to 0.08m, arc angle between 30° to 60°) to maintain effective centrifugal separation across a range of flow velocities. These parameter adjustments ensure that gas separation reliability is preserved even when flow velocity increases to meet higher medium demand.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures reliable gas separation with minimal space requirements, effectively preventing gas spread and ensuring safety by stopping fluid flow when necessary, even at higher flow velocities.
Implementation Method 1
gaseous and liquid components of the fluid are separated from one another before they enter the main chamber (40) by utilizing centrifugal forces acting on the flowing fluid
Implementation Method 2
The gas separation device allows gas flowing with the medium in the supply system to be removed via the latter. The gas separation device of DE 10 2020 103 743 A1 has a large, vertically oriented housing with an inlet and an outlet. Using gravity, the lighter gas collects in an upper collection area of a main chamber

AI summary
The invention provides a gas separation device 100 for separating gas from a hydraulic piping system 300, comprising a housing body 1 which in turn includes an inlet 10, a main chamber 40 and an outlet 50, which are part of a flow path for a fluid flowing through the housing body from the piping system 300. The housing body 1 has a separation section 20 in a transition area between the inlet 10 and the main chamber 40, which is arc-shaped, such that the flow path enters the main chamber 40 from an inflow direction of the inlet 10 in an arc, in order to at least partially separate gaseous and liquid components of the fluid from each other before entering the main chamber 40 by utilizing centrifugal forces acting on the flowing fluid.
