Vane Pump Multi-Pressure Discharge Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vane pump devices that discharge working fluids at multiple pressures require complex configurations for multiple discharge outlets, making it difficult to connect guide members efficiently, as existing designs often necessitate outlets to face different directions, increasing the complexity and size of the pump housing.
Innovation Solution
A vane pump design with a pump unit that discharges working fluid at two different pressures, where the high-pressure discharge outlet and low-pressure discharge outlet face the same direction, allowing for easier connection of guide members and a more compact housing configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple discharge outlets are provided at different positions facing different directions, then the pump can discharge working fluid at multiple pressures, but the complexity of connecting guide members increases and the housing size increases
Solution Approach 1:
The patent merges multiple discharge outlets into a unified directional arrangement where all outlets face the same direction. The housing integrates first and second discharge outlets on the same surface, allowing guide members to be connected in a unified manner rather than requiring separate directional connections for each pressure level.
Solution Approach 2:
The housing design provides universal discharge orientation for all pressure levels. By making all discharge outlets face the same direction, the housing creates a universal connection interface that simplifies the guidance system design and reduces the number of specialized connection points required.
2Adaptability or versatility
If multiple discharge outlets are provided at different positions facing different directions, then the pump can discharge working fluid at multiple pressures, but the housing size increases
Solution Approach 1:
The patent merges multiple discharge outlets into a unified directional arrangement where all outlets face the same direction. The housing integrates first and second discharge outlets on the same surface, allowing guide members to be connected in a unified manner rather than requiring separate directional connections for each pressure level.
Solution Approach 2:
The patent optimizes the spatial arrangement of discharge outlets by positioning them on the same surface plane rather than distributing them across multiple faces of the housing. This dimensional optimization reduces the overall housing footprint while maintaining multi-pressure discharge functionality.

AI summary
An embodiment provides a vane pump device includes a pump unit that includes a high pressure side discharge through-hole which discharges oil at a first discharge pressure, and a low pressure side discharge through-hole which discharges oil at a second discharge pressure lower than the first discharge pressure; and a housing which accommodates the pump unit, and includes a high pressure side discharge outlet through which oil discharged from the high pressure side discharge through-hole of the pump unit is discharged to the outside, and a low pressure side discharge outlet through which oil discharged from the low pressure side discharge through-hole is discharged to the outside, and in which the high pressure side discharge outlet and the low pressure side discharge outlet are formed to face the same direction.
