Integrated Compressor Pump Unit Series Power Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted equipment, such as compressors and pumps, are typically independently mounted, leading to inefficiencies and clutter in the undercarriage space, as they require separate power transmission from the engine, which can be inefficient and occupy more space.
Innovation Solution
An integrated compressor and pump unit is designed, where the compressor and pump are mounted in series, sharing a common rotary input shaft connected to the vehicle's power source, allowing simultaneous operation and efficient use of space by transferring rotary motion from the power take-off shaft to both units, with fluidic sealing to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If compressors and pumps are independently mounted in separate locations, then each unit can be individually maintained and replaced, but the undercarriage space becomes cluttered and mechanical inefficiencies increase due to separate power transmission requirements
Solution Approach 1:
The patent combines the compressor and pump into a single integrated unit with a common housing and shared power input shaft. The compressor and pump are mounted in series on the same housing, allowing both units to be driven simultaneously by a single power source (PTO shaft), thereby reducing undercarriage clutter and eliminating the need for separate power transmission systems while maintaining individual operational capability through separate fluid pathways
2Adaptability or versatility
If separate power transmission systems are used for compressor and pump, then each unit can operate independently, but mechanical inefficiencies increase and more space is occupied
Solution Approach 1:
The integrated design merges the power transmission system into a single input shaft that drives both the compressor and pump simultaneously. This eliminates the mechanical inefficiencies associated with multiple separate power transmission systems (belts, gears, or shafts) while maintaining the ability of each unit to operate independently through separate fluid pathways and discharge points
Solution Approach 2:
The common power input shaft serves multiple functions by simultaneously driving both the compressor and pump units. This multi-functional design reduces the overall complexity of the power transmission system and improves mechanical efficiency by eliminating redundant transmission components while preserving the independent operational versatility of each unit

AI summary
An integrated compressor and pump unit suitable for installation on a vehicle and draw rotary power from a power source of the vehicle. The unit includes a compressor unit and a separate pump unit. The compressor unit has a rotary input shaft coupled to a rotary compressing device of the compressor unit. The pump unit is mounted to the compressor unit and has a rotary input shaft coupled to a rotary pumping device of the pump unit. The pump unit is secured to the compressor unit and rotary motion is transferred from the rotary input shaft of the compressor unit to the rotary input shaft of the pump unit such that the rotary compressing and rotary pumping devices operate in unison and in series.
