Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors face issues with condensate accumulation in the cylinder head chamber, leading to potential leakage and damage, and existing solutions like heating the cylinder head or using drain valves are costly, cumbersome, or degrade lubrication properties.
Innovation Solution
A compressor assembly with a condensate collection chamber and a gravity-driven condensate drain pipe that maintains equal pressure with the cylinder head chamber, allowing continuous condensate drainage during operation without moving parts or valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cylinder head is heated to prevent condensate formation, then condensate accumulation is reduced or prevented, but energy consumption increases and additional servicing is required
Solution Approach 1:
The invention extracts the harmful condensate from the cylinder head chamber by providing a drainage connection to a condensate collection chamber, removing the need to prevent condensate formation through heating while still achieving protection against condensate damage
Solution Approach 2:
The invention introduces a condensate collection chamber as an intermediary component between the cylinder head chamber and the environment, allowing condensate to be collected and managed without requiring energy-intensive heating systems
2Object-affected harmful factors
If a spring-loaded drain valve is used to drain condensate, then condensate can be removed from the cylinder head chamber, but the solution only works when the compressor is non-operative and requires pressure drop
Solution Approach 1:
Instead of using a valve that opens when pressure drops (conventional approach), the invention inverts the approach by providing a constant open drainage path through a connection to a collection chamber, allowing drainage to occur regardless of pressure conditions or operational state
Solution Approach 2:
The invention ensures continuous drainage capability by maintaining an always-open connection between the cylinder head chamber and the condensate collection chamber, eliminating the intermittent operation of spring-loaded valves that only drain during non-operative states
3Object-affected harmful factors
If a drain valve connecting cylinder head chamber to oil sump is used, then condensate can be drained, but lubrication properties of the oil are degraded
Solution Approach 1:
The invention segments the drainage system into a separate condensate collection chamber, preventing condensate from mixing with the lubricating oil in the oil sump and thus preserving lubrication quality while still achieving effective condensate removal
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents condensate leakage and minimizes damage by ensuring continuous drainage, reducing costs and maintenance, and maintaining lubrication quality.
Implementation Method 1
The first end of the condensate drain pipe is at a highest level of the condensate drain pipe and all other parts of the condensate drain pipe are at lower levels so that transport of condensate through the condensate drain pipe takes place under the effect of gravity

AI summary
A compressor assembly includes a compressor of the reciprocating piston type. The compressor includes a cylinder head bounding a cylinder head chamber. Each cylinder head chamber is connected via a condensate drain pipe to a condensate collection chamber so as to form a condensate connection. A first end of the condensate drain pipe is connected with the cylinder head and a second end of the condensate drain pipe is connected with the condensate collection chamber. The first end of the condensate drain pipe is at a highest level of the condensate drain pipe and all other parts of the condensate drain pipe are at lower levels so that transport of condensate through the condensate drain pipe takes place under the effect of gravity.
