Description

(54) ADAPTOR DEVICE FOR OIL TEMPERATURE CONTROL SYSTEM (71) We, SERCK INDUSTRIES LI MITED, a British Company of Warwick Road, Birmingham, England, do hereby declare the invention for which we pray that a Patent may be granted to us and the method by which it is to be performed, to be particularly decsribed in and by the following statement: This invention relates to an adaptor device for inclusion in an oil temperature control system for use particularly in conjunction with a liquid cooled internal combustion engine.
According to the invention, an adaptor device for inclusion in an oil temperature control system comprises a body having a first portion intended for clamping between an engine block and an oil filter in fluid-tight manner and having passages arranged to provide a permanently open flow path through said body portion, in use, between the engine block and filter, the first body portion having a pair of ports communicating with a second body portion defining a chamber containing a thermostatically responsive valve having a valve element, said chamber having ports for connection to a diversion path and one of these chamber ports being normally isolated by the valve element from the ports of the first body portion so as to interrupt the diversion path, the valve being operable, in response to the temperature of oil in said chamber reaching a predetermined value, to move said valve element to a position in which said one chamber port is placed in communication with one of the ports of the first body portion, thereby permitting the flow of oil through said diversion path.
From a second aspect of the invention, an oil temperature control system of an engine comprises an adaptor device as defined in the preceding paragraph mounted between an engine block and an oil filter, said diversion path being connected to a heat exchanger.
The invention will now be described, by way of example, with reference to the accompanying drawings in which: - Figure I is an exploded diagrammatic representation of one form of oil temperature control system of the second aspect of the invention, and Figures 2 and 3 show respectively, to an enlarged scale, part of the interior of one form of an adaptor device of the invention in alternative conditions of operation.
Referring to Figure 1, the oil control system shown therein includes an adaptor device 1 adapted to be located in fluid tight manner between a surface on an engine block 2 and a filter bowl 3 containing a filter element 4 of conventional construction. A permanently open circulatory oil path, indicated by arrows A, is provided between oil ports 6 and 7 of the engine block, the filter 4 being interposed in this path and a pressure relief valve 8 being arranged to interconnect the ports 6 and 7 so that there is always a flow of oil to the engine even if the element of the'filter 4 is completely blocked. A heat exchanger 9 is connected to the adaptor device 1 between an outlet 10 and inlet 11 thereof.
The flow of oil between the circulatory path and the heat exchanger 9 is controlled by a thermostatically responsive valve 13, which is disposed within the adaptor body and shown in more detail in Figures 2 and 3, the filter 4 being omitted. The adaptor device 1 is axially divided by a central partition 1A. A pair of ports 13A and 13B opening respectively at opposite sides of the partition 1A communicate with the interior 13C of the valve 13.
Figure 2 shows the valve in its closed position, which is assumed when the oil is below its normal working temperature, and in this position the valve interrupts oil flow to the heat exchanger 9 but maintains flow through the circulatory path. The valve includes a wax thermostat 14, an enlarged end portion 14a of which co-operates with a valve member in the form of a washer 15, the latter being urged againt a seat 16 by a spring 17 acting between the washer and an end plug 18 abutting a circlip 19 engaged in a groove of the body. A toroidal seal 30 seats in a peripheral groove of the plug 18 and seals against the internal wall 21 of the valve body. The washer, when in the position shown, is interposed between the port 13A and the outlet 10 thereby preventing flow of oil through the heat exchanger 9.
The oil passing through port 13A flows through the valve interior 13C and back into the bowl 3 at the opposite side of the partition through the port 13B whence it passes through the filter 4 and back to the engine via a central passage 22 in conventional manner. The thermostat 14 will remain in this position until the oil flowing therethrough reaches a predetermined working temperature. Wax in the thermostat then melts, causing a pin 20 thereof to be extended against a seat 20a so as to push the valve to the right as seen in Figure 3 against the action of the spring 17, and thus move the washer 15 away from the seat 16, where it places the port 13A in communication with the outlet 10.This effectively places the heat exchanger 9 in parallel with the normal circulatory path indicated by the arrows A, enabling oil to flow through the heat exchanger and back into the path through the inlet 11 after cooling. The inlet 11 brings the oil back to the valve interior 13C whence it passes through port 13B to the filter as before.
It will be appreciated that when the engine oil temperature drops below the aforesaid predetermined temperature as set by initial selection or adjustment of the wax thermostat, the spring 17 returns the washer 15 to its location against the seat 16, thereby once again cutting off the oil supply to the heat exchanger 9.
The adaptor device of the invention can be used as original equipment to establish an oil cooling path in a new engine and has the advantage that it can also be used to provide an oil cooling path in an existing engine. This can be effected rapidly and easily, since the adaptor device can be fitted as a modification simply by removing an existing oil filter bowl and interposing the device between the bowl and engine block, the heat exchanger then being coupled to the adaptor inlet and outlet provided.
Any convenient form of heat exchanger may be employed, such as an intercalary type cooler of a cooler adapted to exchange heat between the engine oil and engine cooling water. Moreover, the valve within the adaptor device can be of any convenient form which permits control of oil flow to the heat exchanger in dependance upon the temperature of the oil.
WHAT WE CLAIM IS: 1. An adaptor device for inclusion inan oil temperature control system, said device comprising a body having a first portion intended for clamping between an engine block and an oil filter in fluid-tight manner and having passages arranged to provide a permanently open flow path through said body portion, in use, between the engine block and filter, the first body portion having a pair of ports communicating with a second body portion defining a chamber containing a thermostatically responsive valve having a valve element, said chamber having ports for connection to a diversion path and one of these chamber ports being normally isolated by the valve element from the ports of the first body portion so as to interrupt the diversion path, the valve being operable, in response to the temperature of oil in said chamber reaching a predetermined value, to move said valve element to a position in which said one chamber port is placed in communication with one of the ports of the first body portion, thereby permitting the flow of oil through said diversion path.
2. An adaptor device according to Claim 1, wherein the ports of the first body portion lie respectively to either side of a partition arranged to divide the interior of the first body portion.
3. An adaptor device according to Claim 2 wherein said valve element is a washer slidable within said second body portion and abutting a shoulder of that body portion in its isolating position.
4. An adaptor device according to any one of the preceding claims wherein the valve is of the wax-filled type.
5. An adaptor device according to any one of the preceding claims wherein the valve element is urged towards its isolating position by spring means.

**WARNING** start of CLMS field may overlap end of DESC **. through the circulatory path. The valve includes a wax thermostat 14, an enlarged end portion 14a of which co-operates with a valve member in the form of a washer 15, the latter being urged againt a seat 16 by a spring 17 acting between the washer and an end plug 18 abutting a circlip 19 engaged in a groove of the body. A toroidal seal 30 seats in a peripheral groove of the plug 18 and seals against the internal wall 21 of the valve body. The washer, when in the position shown, is interposed between the port 13A and the outlet 10 thereby preventing flow of oil through the heat exchanger 9. The oil passing through port 13A flows through the valve interior 13C and back into the bowl 3 at the opposite side of the partition through the port 13B whence it passes through the filter 4 and back to the engine via a central passage 22 in conventional manner. The thermostat 14 will remain in this position until the oil flowing therethrough reaches a predetermined working temperature. Wax in the thermostat then melts, causing a pin 20 thereof to be extended against a seat 20a so as to push the valve to the right as seen in Figure 3 against the action of the spring 17, and thus move the washer 15 away from the seat 16, where it places the port 13A in communication with the outlet 10.This effectively places the heat exchanger 9 in parallel with the normal circulatory path indicated by the arrows A, enabling oil to flow through the heat exchanger and back into the path through the inlet 11 after cooling. The inlet 11 brings the oil back to the valve interior 13C whence it passes through port 13B to the filter as before. It will be appreciated that when the engine oil temperature drops below the aforesaid predetermined temperature as set by initial selection or adjustment of the wax thermostat, the spring 17 returns the washer 15 to its location against the seat 16, thereby once again cutting off the oil supply to the heat exchanger 9. The adaptor device of the invention can be used as original equipment to establish an oil cooling path in a new engine and has the advantage that it can also be used to provide an oil cooling path in an existing engine. This can be effected rapidly and easily, since the adaptor device can be fitted as a modification simply by removing an existing oil filter bowl and interposing the device between the bowl and engine block, the heat exchanger then being coupled to the adaptor inlet and outlet provided. Any convenient form of heat exchanger may be employed, such as an intercalary type cooler of a cooler adapted to exchange heat between the engine oil and engine cooling water. Moreover, the valve within the adaptor device can be of any convenient form which permits control of oil flow to the heat exchanger in dependance upon the temperature of the oil. WHAT WE CLAIM IS:
