pressure feed
Học thuậtThân thiện
Definition
Noun: - A mechanical lubrication system for internal combustion engines where oil is forced into the engine's bearings under pressure by a pump. This system ensures a consistent and reliable supply of lubricant to critical moving parts.
Usage
- This term is used specifically in mechanical and automotive engineering contexts to describe a type of forced lubrication system.
- It functions as a compound noun. The primary usage is as a singular noun (e.g., ), but it can be used in a general sense without an article.
Examples
- Noun:
- The engine utilizes a pressure feed to lubricate the crankshaft and camshaft bearings.
- Older engines sometimes used a splash system, but modern designs almost universally rely on a pressure feed.
- A failure in the pressure feed can lead to catastrophic engine damage due to insufficient lubrication.
Advanced Usage
- The term can be used attributively (like an adjective) to describe other components of the system.
- The pressure feed line was clogged.
- Check the pressure feed pump for proper operation.
Variants and Related Words
- Pressure lubrication (n): A synonymous term for the same mechanical system.
- Forced-feed lubrication (n): Another synonymous term.
- Splash feed (n): An alternative, older lubrication system where oil is splashed onto components, contrasting with a pressure feed system.
- Oil pump (n): The key component that creates the pressure in a pressure feed system.
Synonyms
- Forced lubrication
- Pressure lubrication
- Forced-feed system
Notes
- "Pressure feed" is a technical compound noun. In general language, the verb "feed" and noun "pressure" have many other meanings, but in this specific context, they combine to refer precisely to this mechanical system.
- It is not commonly used in idiomatic expressions or as a phrasal verb in this technical sense.
Noun
- mechanical system of lubricating internal combustion engines in which a pump forces oil into the engine bearings
