Abstract
A system and method for removing gases from an engine coolant system. In one embodiment, the system includes a fluid system that is operable to collects gas, and a gas collection system coupled to the fluid system. The system also includes a venturi pump system coupled to the fluid system and to the collection system, where the venturi pump system is operable to extract the gas from the fluid system via the collection system.
Claims20
An engine coolant system using an engine coolant comprising:
- a fluid system that is operable to collect gas;
- a gas collection system coupled to the fluid system to receive gas from the fluid system;
- and
- a venturi pump system coupled to the fluid system and to the gas collection system, wherein the venturi pump system uses engine coolant flow to extract the gas from the fluid system via the gas collection system.
An engine system comprising:
- an engine;
- and
- an engine coolant system coupled to the engine, the engine coolant system comprising:
- a fluid system including a high portion operable to collect gas;
- a gas collection system coupled to said high portion of the fluid system to receive gas from the fluid system;
- and
- a venturi pump system coupled to the fluid system and to the gas collection system, wherein the venturi pump system is operable to extract the gas from the fluid system via the gas collection system and to send the gas to the engine coolant system.
A method for removing gas from an engine coolant system containing an engine coolant, the method comprising:
- using a fluid system within the engine coolant system to collect gas;
- and
- using a venturi pump system within the engine coolant system to extract the collected gas from the fluid system via gas collection system, wherein the venturi pump system uses engine coolant flow to extract the gas from the fluid system.
