Definitions
- the present invention relates to the field of mechanics and more particularly to motorization machines. It relates more particularly to a regulator device for small thermal engines 2 or 4 times. It specifically relates to a control device for all small heat engines, used mainly on gardening equipment, such as lawn mowers, tillers, water pumps, generators, etc.
- the invention has therefore The object is a device for regulating the engine speed, which consists in modifying the tension of the regulation spring by means of a tension tab which is folded inwards or outwards, under the influence of a tilting means rotatably mounted about an axis of rotation and driving the tension spring about a median position between a tensioning position and an expansion position of the spring.
- the control system according to the invention further comprises a protection device of the housing type, consisting of a plate preventing the collision of all the points of the control system by foreign objects, to hide the system in the eyes of the user, so that it is not tempted to change the setting, and thus to disrupt it, and thus make it very difficult to change the engine speed adjustment without having appropriate tools.
- the tension tab is in the form of a rigid metal plate, terminated by a deformable arm where is fixed the tension spring. The tension spring is secured at the other end to the tilting lever controlled by the regulating pin exiting the engine cylinder.
- the present device ensures the increase or decrease of decreasing the tension of the control spring and, consequently, the speed of the motor by folding a tab which acts on the tension of the control spring.
- the device according to the invention therefore aims to simplify the throttle control and the adjustment of the maximum speed of the engine, significantly reduce manufacturing costs, improve the accuracy of the engine speed adjustment for better compliance with the "noise" standard of the gardening equipment on which the motor is applied and, at the same time, to improve the protection of the assembly so as to prevent, and even forbid the unsuspecting user to make any changes as well caused by an accidental cause as resulting from a voluntary intervention of the user.
- the device according to the invention is intended to be used on small, overturned (OHV) or overhead camshaft (OHC) thermal motors. A particular application is thus achieved, namely the maintenance of a fixed speed on OHN engine and OHC engine.
- the single figure shows in plan the control device according to the invention.
