OIL-CIRCUZATING SYSTEM FOR LUBBICATING AND REGULATING.
specification of Letters Patent.
Application. led July-28, 1911. Serial No. 641,188.
cated by a forced circulation of oil, and in which also theregulating valves are operated by a'motor actuated by oil under pressure andcontrolled by the speed governor of the motivepower device. It has been proposed to combine these features by using a single oil pump to feed the bearings and the valve-actuating motor. Y I-Ieretofore, Ahowever, it has been necessary to insert a throttling or pressure-reducing device in the lubricating portion of the systemin order to prevent too great. an oil pressure on the bearings and yet maintain an operative pressure in the valve-actuating motor.
The object of the present invention is to avoid the waste of power involved in pumping all the time against the resistance of the pressure-reducing device. The mass of oil remains uniform, being conveyed at all times through the motor-controlling valve, and supplied to the bearings at uniform pressure. The only variation in load on the pump is that due to the resistance offered by the valve-motor when it is brought into operation by the governor. The entire amount of oil is available both for'lubricating and for operating the valve-motor.
The accompanying drawing is a diagrammatic illustration of a system embodying my invention.
The oil is drawn from a tank 1 by means of a pump 2 which preferably of the -roositive pressure on the oil in the pipe 3 su cient to actuate the piston 4 in the cylinder 5 of the valve-motor;
' the piston 41 of said motor being connected tomechanism, not shown, for operating the controlling valve or valves of the steam enf gine 6. The pipe 3 delivers 'the oil t0 the casing 7 of the regulating valve 8 of the motor; said valve being preferably of the piston type, having two pistons 9 attached to a stem 10, and located on each side of the oil inlet. The pistons, in their central position, are in line with the ports 11 leading to the ends of the cylinder 5 of the valvemotor. The stem 10 is pivoted to a floating lever 12, one end of which is pivoted to the piston rod 41 and the other end to the movable collar of the speed governor 13. When Patented Feb. l13, 1912.
the valve v8 is shifted by said governor, it is returned to its normal position by the piston rod and the floating lever, in a wellknown manner. The ends of the valve cas-- ing 7 above and below the pistons 9 are connected to the pipe 14 which conveys oil to the shaft bearing 15 of the engine. A drain pipe16 returns the oil to the tank 1.
In order to-permit a flow of oil to theA lbearing, bypasses are provided around the plstons 9 when in their central position. The bypasses I prefer are notches 17 in flanges on the pistons 9. Said notches communicate with the ports 11 when the pistons are in their central position, and permit the oil to have free access to the upper and lower sides of the motor piston 4, and also to flow from the pipe 3 to the pipe 14, and thence to the bearing or bearings. When the valve 8 is moved by the governor to connect only one port 11 with the Supply pipe 3 and the other with the pipe 14 only, the unbalanced pressure on the motor piston 4 causes said` piston to move, and the oil which it displaces is forced through the pipe 14 to the bearing. The supply of lubricant for said bearing is thus maintained constant. In case there is danger of back v pressure in the pipe 3 when t-he valve 8 is shifted, a safety valve 18 can be easily in- Idesire to have it understood that the app paratus shown is only illustrative, and that the invention can be carried out by other means.
W'hat I claim as new and desire to secure by Letters Patent of the United States is 1. The combination with a system of forced lubrication, of a valve-actuating motor operated by the lubricant, and apregulating valve for said mot-o1' which permits the lubricant to iow through it in its central position. y
2. The combination with a system of forced lubrication, of a valve-actuating inotor operated by the lubricant, and a regulat ing valve for said motor; comprising pistons which in their central position have bypasses around them.
3. The combination withA a system of forced lubrication, of a valve-actuating motor, a valve casing for said motor interposed in the path of the lubricant, and a regulating valve in said casing which permits'a free flow of the lubricant except when it is shifted to cause said lubricantto operate said motor.
4. The combination with a system of lforced lubrication, of a valve-actuating motor, a valve-casing for said motor provided with ports, a regulating valve in said casing 5. The Vcombination With a system .of
forced lubrication including a pump, of a valve-actuating motor, a regulator for the motor comprising a casing through which fluid from the pump continuously flows, and a valve in the casing which controls the distribution ofy iuid'to thelubricating system and also to the motor.
In witness whereof, T. have hereunto set my hand.
