Ball Float Vent Valve for Hydraulic Suction Line Air Purging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic systems face issues with trapped air causing performance problems and component failure due to air being forced through hydraulic pumps, despite prior solutions not providing a universal solution for air expulsion in systems of varying sizes and shapes.
Innovation Solution
A ball float vent valve with a valve body having an axial passageway defined by a cylindrical inlet and outlet chamber connected by a tapered seat, featuring a spherical float that seals the passageway and a retainer to retain the float, allowing air to escape while preventing re-entry, suitable for installation on suction tubes or lines in hydraulic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air is allowed to escape from hydraulic suction lines, then air removal effectiveness is improved, but system sealing is compromised
Solution Approach 1:
The valve employs a floating ball mechanism that dynamically opens and closes the vent passage based on air pressure differential. When air pressure exceeds a threshold, the ball lifts to open the passage; when air is purged, the ball returns to seal the passage, achieving both air removal and system sealing
Solution Approach 2:
The vent valve operates automatically using the air pressure itself to drive the floating ball mechanism, eliminating the need for external control systems or additional energy input while maintaining both air purging and sealing functions
2Reliability
If a vent valve is installed on suction lines, then air purging capability is improved, but device complexity increases
Solution Approach 1:
The invention extracts only the essential air venting function from complex automated valve systems, using a simple floating ball mechanism that relies on natural pressure differential rather than external actuators, control systems, or power sources
Solution Approach 2:
Instead of using a complex mechanism to force the valve open for air purging, the invention inverts the approach by using a simple floating ball that naturally rises when air pressure builds, allowing the air pressure itself to open the valve and simplify the overall structure

Function Achieved in This Case
Effectively allows air to escape from hydraulic suction lines while maintaining a sealed system, preventing air from re-entering and reducing the risk of pump component damage, enhancing pump reliability and system durability.
Implementation Method 1
A spherical float positioned in the outlet chamber may be dimensioned to seal the passageway when seated on the tapered seat
Implementation Method 2
a tapered seat connecting the inlet chamber and outlet chamber. The spherical float may be dimensioned to seal the passageway when seated on the tapered seat

AI summary
A ball float vent valve includes a valve body having an inlet port, an outlet port and an axial passageway there-between. The passageway may be defined by a cylindrical inlet chamber, a cylindrical outlet chamber and a tapered seat connecting the inlet chamber and outlet chamber. The outlet chamber may include an annular retaining groove proximate the outlet port. A spherical float may be positioned in the outlet chamber. The float may be dimensioned to seal the passageway when seated on the tapered seat. A retainer positioned in the retaining groove may include an outer crescent region having a plurality of apertures, a center region dimensioned to retain the float in the outlet chamber, and a linking region connecting the outer region to the center region.
