Variable Pump Stop Stroke Using Pressure-Differential Feedback

The patent applies dynamics by making the minimum displacement stop variable rather than fixed. The stop position is dynamically adjusted based on the pressure differential across the pump, allowing the system to adapt to different operating conditions. This resolves the contradiction by enabling temperature control at high pressures while reducing parasitic energy loss at lower pressures through automated adjustment of the minimum displacement.

The patent implements feedback through a pressure differential sensing mechanism that automatically adjusts the minimum displacement stop position. The system senses the pressure differential and provides feedback to modify the stop position accordingly, creating a closed-loop control system that optimizes both temperature control and energy efficiency across varying operating conditions.

The patent makes the minimum displacement stop dynamic rather than static, allowing it to vary with operating conditions. This enables the pump to maintain adequate flow for temperature control while avoiding excessive minimum displacement settings that would cause non-linear mechanical efficiency losses, thereby resolving the contradiction between temperature control and mechanical efficiency.

The patent changes the parameter of minimum displacement based on operating conditions (pressure differential). By adjusting this key parameter dynamically, the system optimizes the balance between maintaining sufficient flow for cooling and minimizing mechanical efficiency losses associated with operating at fixed minimum displacement settings.

The patent introduces a pressure differential sensing and feedback mechanism that automatically adjusts the minimum displacement stop. This feedback-based approach provides adaptability to varying pressure conditions while keeping the control system relatively simple, as the adjustment is automated rather than requiring complex external control systems.

The system applies self-service by using the pump's own operating parameters (pressure differential) to automatically adjust its minimum displacement setting. The pump essentially regulates itself based on its operating conditions, eliminating the need for complex external control systems while maintaining high adaptability to varying pressure conditions.
