Problems solved by technology

However, these bypass valves may not be suitable for this function
Sometimes, the valve is opened so that the coolant cannot be filtered
At other times, the valve remains closed, preventing the coolant from circulating, which can overheat the engine or transmission
Further, bypass valves placed in the coolant lines can be large and bulky, adding cost and complexity during installation
They may also need to be replaced frequently, increasing the cost and time of replacement repairs

Embodiment Construction

[0017] The invention will now be described with reference to the drawings, in which like reference numerals refer to like parts throughout. Embodiments according to the invention provide a fluid filter, in particular a coolant filter, which ensures sufficient fluid flow to a heat exchanger. The filter can be used coaxially in the application. Also, it can be used on the pressure side or the return side of the application mechanism. The filter has a simple structure, is easy and simple to install, and requires less maintenance or is not complicated during use.

[0018] An embodiment of the device of the present invention is illustrated in FIG. 1 . Specifically, FIG. 1 is a schematic diagram of a fluid filter 10 applied in an automobile cooling system. Filter 10 is placed in series with transmission case 12 and heat exchanger 14 . The heat exchanger 14 may be a cooler or radiator. Conduit 20 allows filter 10 to be in fluid communication with transmission case 12 via transmi...

Abstract

A fluid filter includes a filtered flow and a bypass flow. In particular, a fluid filter insert includes a first end cap, a second end cap, a screen disposed between the first and the second end caps, and a filter media surrounding the screen. Further, a method of filtering a fluid includes passing a first portion of the fluid through a fluid filter inlet, passing a second portion of the fluid through a filter media, and passing the first and the second portions through a filter outlet. In addition, a fluid filter includes a bypass inlet, a filter media inlet coaxial with the bypass inlet, an outlet axially spaced from the bypass inlet, and a housing surrounding the bypass inlet, the filter media inlet and the outlet. Further, the fluid filter provides that the bypass inlet is dimensioned to permit a predetermined amount of flow.

Description

technical field [0001] The present invention relates generally to automotive fluid circuits. More specifically, the present invention relates to an in-line fluid filter for an automotive fluid circuit. Background technique [0002] A car's engine and transmission can generate a lot of heat. In particular, heat can reduce the effectiveness of the lubricating oil of the engine or transmission. Weakened lubricants can have undesired consequences, potentially causing catastrophic damage to the engine or transmission. Other types of machines also require heat removal. [0003] Accordingly, cooling systems have been provided to remove excess heat generated by the engine, transmission or machinery. Specifically, coolant may flow through a heat exchanger to remove such heat. A heat exchanger for an engine is generally called a radiator. The heat exchanger of the transmission case is generally called the oil cooler. [0004] The coolant circulates through the radiator or oil c...
