Engine system having coolant control valve
First Claim
Patent Images
1. An engine cooling system comprising:
- a coolant control valve device including;
a valve housing including a coolant inflow chamber therein;
a plurality of valves that distribute coolant flowing into the coolant inflow chamber to coolant demand elements, respectively;
a driver that is engaged with the plurality of valves and operates each of the plurality of valves;
a safety valve disposed in the valve housing and bypassing the coolant toward a degassing passage connected to the coolant inflow chamber, by selectively opening or closing the degassing passage, the safety valve being operated by a coolant temperature of the coolant flowing into the coolant inflow chamber, wherein the degassing passage is formed at a passage formed in the coolant inflow chamber and configured for forwarding the coolant to a radiator so that a part of the coolant forwarded to the radiator is bypassed to the degassing passage; and
a degassing storage that is connected to the degassing passage and collects coolant including a bubble supplied from the coolant control valve device through the degassing passage,where the valve housing stores the plurality of valves, the driver, and the safety valve.

Abstract
An engine system having a coolant control valve device may include valves that distribute coolant that is injected into a coolant inflow chamber to coolant demand elements, respectively; a driver that operates each of the valves; a safety valve that bypasses coolant that is operated by a coolant temperature to be injected into the coolant inflow chamber; and a degassing member that collects coolant including a bubble, wherein a degassing passage that is opened or closed by operation of the safety valve is formed.

10. An engine cooling system comprising:
a coolant control valve device including; a valve housing including a coolant inflow chamber therein; a plurality of valves that are disposed at the valve housing to distribute coolant flowing into the coolant inflow chamber to coolant demand elements, respectively; a driver that is engaged with the plurality of valves and lifts each of the plurality of valves to enable each valve to open or close passages formed in the coolant inflow chamber; a safety valve that is disposed in the valve housing and disposed at an emergency passage that forwards the coolant flowing into the coolant inflow chamber toward a radiator, the safety valve being operated by a coolant temperature of the coolant flowing into the coolant inflow chamber; and a degassing storage that collects coolant including a bubble supplied from the safety valve through a degassing passage connected to the coolant inflow chamber, wherein the degassing passage is formed at an internal side surface of the emergency passage and is connected with the degassing storage, such that a bubble included in the coolant is forwarded to the degassing storage when the coolant flows to the radiator through the emergency passage by an operation of the safety valve. - View Dependent Claims (11, 12, 13)
