Problems solved by technology

[0007] However, in the bypass valve applied to the conventional transmission fluid cooling system as described above, since each constituent element needs to be sequentially assembled and assembled to the valve mounting hole of the valve housing, there is a disadvantage that it is difficult to precisely position Each constituent element requires excessive assembly time and increases manufacturing cost
[0008] In addition, the bypass valve applied to the transmission fluid cooling system also has the disadvantage that when the transmission fluid does not need to be cooled, due to the low temperature transmission fluid cooled by the oil cooler, a part of the transmission fluid flows from the transmission into the bypass valve and is then in contact with the The bypass transmission fluid in a high temperature state flows into the transmission together, so rapid temperature rise of the transmission fluid is difficult
[0009] In addition, since the conventional bypass valve is located in the flow passage pipe connecting the transmission and the oil cooler, and a relatively large bypass valve is located in the pipe, there is also a disadvantage of deteriorating the space utilization of the engine room

Abstract

The invention discloses a valve apparatus for a vehicle. The valve apparatus for the vehicle includes a housing having open and closed ends to form an interior space, and formed with first and second intake ports receiving a transmission fluid from a transmission and an oil cooler, a bypass port bypassing the transmission fluid to the transmission, and an exhaust port exhausting the transmission fluid to the oil cooler, an inner cap inserted at least partially into the interior space, fixed to the housing, and having an open hole inserted into the interior space, an operation unit disposed between the inner cap and the closed end of the housing, and reciprocally moves according to a transmission fluid temperature, a valve unit disposed in the operation unit to selectively open and close the bypass port and the exhaust port depending on a movement of the operation unit; and an elastic member interposed between the inner cap and the operation unit.

Description

technical field [0001] The present invention relates to a valve device for a vehicle. Background technique [0002] In general, a valve is a device installed in a pipe or container to allow the inflow of fluids including gases such as air and liquids such as water, and to discharge or prevent the inflow of fluids to the outside, to control the flow of fluids flow rate and pressure. [0003] Typically, such valves are configured to be able to control the flow of fluid by manipulating the valve seat through which the fluid passes using a valve stem and handle, or to be able to be remotely adjusted by sensing the temperature of the fluid flowing through the valve seat using a separate temperature control device. [0004] Meanwhile, in recent years, a valve capable of being controlled according to temperature as described above has been applied to a cooling apparatus for cooling transmission fluid such as transmission oil. [0005] Conventional transmission fluid cooling syste...
