The present invention relates to an oil temperature control valve having an oil filter, and in particular, an oil filter cartridge is installed on one side of the valve body to achieve simplicity in manufacturing, reduction in manufacturing cost, and improved reliability by simplifying the hydraulic line. The focus is on the ham.

Oil line systems in hydraulically driven equipment such as air compressors use oil temperature control valves and oil coolers to prevent overheating of the oil filter assembly and operating oil.

In the related art, as shown in FIG. 1, the oil filter assembly 100 and the oil temperature control valve 102, which are composed of a head located at an upper side and a cartridge located at a lower side, are separately located and connected to each other via a pipe component 101. have.

Therefore, the oil separated from the air and oil separation tank is filtered by removing impurities in the cartridge through the head of the filter assembly 100, and then enters the oil temperature control valve (1) through the piping parts (101). When the temperature of the introduced oil is less than the reference value bypasses the compressor through the first output port 103, and if more than the reference value is transferred to the cooler through the second output port 104 to cool below the set value and then supplied to the compressor side I am trying to.

However, since the oil filter assembly 100 and the oil temperature control valve 102 are separately installed as described above, there are inconveniences in manufacturing and installation, as well as manufacturing cost is increased, and the two parts are connected to each other by piping. Therefore, there is a problem in that the installation space is required accordingly and the phenomenon of leakage at the connection occurs to reduce the quality of the product.

Therefore, the object of the present invention is to solve the conventional problems as described above, and to provide an oil temperature control valve integrally configured with an oil filter, as described in detail in the accompanying example drawings as follows.

As shown in FIGS. 2 and 3, the oil filter 9 is screwed and installed on the upper side of the valve body 1, and the distal end of the input port 2 is elongated to be connected to the suction port side of the oil filter.

In addition, while forming the space portion 3 below the oil filter discharge port inside the body, the second output port 5 connected to the oil cooler 12 is formed at one upper portion thereof, and the compressor 10 at the lower portion thereof. And a first output port 4 directly connected to it.

In addition, a flow path distribution device is installed in the space 3 to sense the temperature of the oil flowing from the filter and discharge the oil to the corresponding output port. The first and second output ports 4 and 4 are respectively provided on upper and lower sides of one wall. 5) and a regulator 8 having discharge holes 8a and 8b penetrated therein so as to restrain upward and downward sliding in the space portion 3, and a compression coil type return spring 7 at the lower portion thereof. It is comprised by connecting and installing the summer staff 6 which were made.

Looking at the operating state of the present invention configured as described above with reference to Figures 2 and 4 and 5 as follows.

The mixed fluid of compressed air and oil in the compressor (10) is separated into pure air and oil in the air oil separation tank (11), and then the air is discharged to the operating part requiring compressed air, and the oil is discharged in the system of the equipment. While continuously flowing, the cycle operation flowing into the compressor is performed.

At this time, the oil from the air oil separation tank (11) enters the oil filter (9) through the input port (2) of the valve body (1) and filters the impurities contained therein, and then the regulator of the space (3) ( 8) flows into. At this time, since the temperature of the oil is not high at the initial stage of operation, the volumetric deformation of the thermal state does not occur. Done. (See Figure 2 (a).)

Subsequently, when the temperature of the oil rises due to the continuous operation of the equipment, the upper side of the dust stat 6 is pushed up, pushing the regulator 8 which is in contact with it.

When the regulator 8 rises, the first discharge hole 8a is reduced in the penetration area with the first output port 4, and the hole 8a is penetrated with the second output port 5 in FIG. Some cooling actions are performed while simultaneously discharging to both side ports (see FIGS. 5A and 2B). If the temperature of the oil is increased by more than the set value by the continuous circulation action, the summer stat 6 detects this and pushes the regulator 8 to the uppermost bar. The first discharge hole 8a is blocked and the second discharge Since only the hole 8b penetrates through the second output port 5, the oil is cooled through the cooler 12 and then supplied to the compressor 10 (see FIGS. 5 (b) and 2 (c)). ).

When the compressor is idle or the equipment is stopped, the temperature of the oil is lowered and the second output port 5 is blocked by the original state of the thermal state 6, and the first output port 4 is opened. Oil is bypassed without cooling (see Figure 2 (a)).

The present invention, which is constructed and operated as described above, improves the structure of the temperature control valve and installs the filter on one side thereof, thereby eliminating the pipes that were previously connected and installed, thereby simplifying and simplifying the installation. It is possible to reduce costs, to prevent leakage of pipes, and to compact oil lines.
