Abstract
The utility model belongs to the class of mechanical engineering. The utility model particularly a lubricating oil pressure compensator for an internal combustion engine, comprising a compensating oil pump, an oil pipe, a one-way valve, and a hydraulic control switch. The compensating oil pump is connected with an oil pool of an internal combustion engine through an oil inlet pipe. An oil outlet pipe on which the one-way valve is provided is connected with a lubricating system of the internal combustion engine. The oil outlet pipe of the original lubricating system is provided with the one-way valve and the hydraulic control switch which controls a control circuit of the compensator. Before the internal combustion engine is started and stopped, the utility model lubricates the internal combustion engine, which can effectively prevent moving parts from being worn caused by dry friction. The service life of equipment is extended.
Description
The utility model belongs to mechanical engineering, particularly relates to a kind of internal combustion (IC) engine lubricating oil pressure compensator.
At present, the lubrication system of various internal-combustion engines all is behind internal combustion engine start, be lubricated for each moving surface by the internal-combustion engine drives oil pump, internal-combustion engine is to be in dry condition between each moving element surface when starting basically like this, it is very serious to wear and tear, and reduced much the working life of each parts.The number of patent application of Patent Office of the People's Republic of China's bulletin on October 14th, 1992 is 92203676.4 " internal-combustion engine self-pressure type preoiler "; it has two lubrication oil casees; in fuel tank, have into and out of oil pipe; form by solenoid valve, hydraulic pressure circuit breaker, hydraulic switch etc. on the fuel tank cap; when engine operation; by the oil that lubricating pump supplies with certain pressure for two fuel tanks, when motor quit work, the pressure oil of two fuel tanks just can and be shut down the back before start motor is lubricated.The deficiency of this device is pressure oil in the fuel tank when supply engine is lubricated, and service time and oil mass are limited, can not give motor lubricated fully.
The purpose of this utility model is to provide a kind of the normal lubricated of lubricating system of IC engine that guarantee before internal combustion engine start and before stopping.
The technical solution of the utility model is: a kind of internal combustion (IC) engine lubricating oil pressure compensator, comprise the compensation oil pump, oil pipe, one-way valve, hydraulic switch, it is characterized in that the filler opening that compensates oil pump is connected with the internal-combustion engine oil sump by oil inlet pipe, compensation oil pump oil outlet is connected with lubricating system of IC engine by oil outlet tube, one-way valve is installed on the oil outlet tube, one-way valve and hydraulic control switch are installed on the oil pump outlet line of former lubrication system, control the compensator control circuit by the hydraulic control switch, the compensator control circuit is by power supply, ignition switch, hydraulic control switch and light-emitting component are formed, normally-closed contact and light-emitting component, the contact and the power supply of compensation Oil pump electrical machinery and ignition switch are formed a loop, normally opened contact and starting electrical machinery, another contact of ignition switch and power supply are formed.
Advantage of the present utility model is: before internal combustion engine start, be lubricated for each moving element of internal-combustion engine with the compensation oil pump earlier, when the pressure of lubrication system reaches one regularly, can starting apparatus combustion engine, before internal-combustion engine stops, when lubrication system pressure reduces, the compensation oil pump will be to the lubrication system supercharging, each moving element is turned round under the situation well lubricated, and reduced each parts because the wearing and tearing that dry friction causes, the working life of having improved each parts.
Embodiment of the present utility model is explanation in detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is the utility model lubrication system principle schematic.
Accompanying drawing 2 is the utility model compensator control circuit schematic representation.
As accompanying drawing 1, shown in 2, the filler opening of compensation oil pump 8 links to each other with internal-combustion engine oil sump 11 by oil inlet pipe 10, before internal combustion engine start, connect by the circuit that ignition switch 13 turns to K1 will compensate oil pump M2, by power supply 14 power supplies, at this moment the normally-closed contact K3 of hydraulic control switch 4, K4 connects, light-emitting component 12 is shinny, motor M 2 drives compensation oil pump 8 and rotates, lubricant oil is sucked from internal-combustion engine oil sump 11 by oil inlet pipe 10, enter lubricating system of IC engine 1 by oil outlet tube 5 and the one-way valve 6 on it, when oil pressure reached certain value, the normally-closed contact of hydraulic control switch 4 disconnected, connect normally opened contact K5 simultaneously, K6, at this moment light-emitting component 12 extinguishes, and motor M 2 stops operating, and illustrates that the lubricated of internal-combustion engine finish, at this moment just can turn to K2 starting electrical machinery M1 to connect by ignition switch 13, internal combustion engine start, at this moment the lubricant oil of internal-combustion engine just can be by oil pump 9 through one-way valve 7 and hydraulic control switch 4, and oil inlet pipe 3 is given internal combustion engine lubrication.When but the pressure of pressure gauge 2 display systems, one-way valve 7 can prevent to compensate oil pump 8 startups, lubricant oil entered oil pump 9 and returns internal-combustion engine oil sump 11.
