Solution Overview
Problem
Conventional pressure boosters have limited design flexibility due to the requirement of electrical means for switching operations and may consume excessive pressurized fluid, with potential for noise and leakage issues.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical means including reed switches and solenoids are used for switching operations, then switching control can be achieved, but the device complexity increases and electrical wiring is required
Solution Approach 1:
The patent replaces the electrical switching system (reed switches and solenoids) with a purely mechanical valve actuation system. The drive piston directly mechanically actuates the operating valve through a pushrod, eliminating the need for electrical wiring and electromagnetic components while maintaining effective switching control of the pressurized fluid supply.
2Adaptability or versatility
If the booster cylinder and drive cylinders are integrated with same diameter, then structural simplicity is maintained, but design flexibility is limited
Solution Approach 1:
The patent segments the cylinder system into distinct functional components: a booster cylinder for compressing pressurized fluid and separate drive cylinders for actuating the valves. This segmentation allows each cylinder to have optimized dimensions for its specific function, with the drive cylinder inner diameter being different from the booster cylinder inner diameter, thereby enhancing design flexibility.
3Force
If pressurized fluid is continuously supplied to drive cylinders, then driving force is maintained, but fluid consumption increases
Solution Approach 1:
The patent implements periodic action by supplying pressurized fluid to the drive cylinder only during specific phases of the operational cycle when driving force is required. The operating valve controls timed intervals of fluid supply, allowing the drive piston to accumulate force during supply phases and maintain motion during non-supply phases, thereby reducing overall fluid consumption while sustaining the necessary driving force.

AI summary
A pressure booster having arranged therein drive cylinders on both sides of a boosting cylinder is provided with a pair of pilot valves that are actuated when pistons of the drive cylinders abut against the moving ends thereof. A pair of actuation valves switch the supply state of a pressure fluid to pressure chambers of the drive cylinders. When the pilot valves are actuated, the pressure fluid passes through the pilot valves and is supplied to the pair of actuation valves, and the supply state of the pressure fluid is switched.
