Abstract
A fuel pressure balancer mainly solves the problems that an existing fuel pressure balancer is poor in sealing effect and poor in noise reduction effect. The fuel pressure balancer is characterized in that a plastic shell (1) is in a cylindrical funnel shape, and the upper portion of the plastic shell is connected with a plastic end cover (3), a plastic piston (4) is arranged in an upper inner cavity of the plastic shell (1), and a spring (5) is arranged between the plastic piston (4) and the plastic end cover (3); the corresponding faces of the plastic piston (4) and the plastic end cover (3) are provided with a first boss (6) and a second boss (7) respectively, and the two ends of the spring (5) are clamped on the first boss (6) and the second boss (7) respectively. The fuel pressure balancer has the advantages of being simple in structure, small in occupied space, convenient to machine, and suitable for being used in small gasoline engines.
Description
Technical field
The utility model relates to the hydraulic shock absorber in a kind of engine fuel conveying pipe road, is specifically related to a kind of fuel pressure balace weight.
Background technique
Petrolic fuel delivery is to enter into oil sprayer by oil pipe, and then entering firing chamber by spark ignitor, fuel oil can produce pressure surge in course of conveying, to making the fuel feeding of motor occur fluctuation, the output shaft rotating speed of motor is not steady, and then occurs larger vibration, noise.Fuel pressure balace weight is to make fuel pressure attenuate pulsations, eliminates fuel oil transmissions of pulse in conveyance conduit, and fuel delivery is stablized, and makes engine mildness, reduction noise.Existing fuel pressure balace weight is mainly comprised of housing, diaphragm, spring and adjusting screw, diaphragm is divided into grease chamber and two chambers of air chamber by housing, in air chamber, be provided with spring, adjusting screw is connected with the first spring seat, diaphragm is fixed on the second spring seat, and spring is between the first spring seat and the second spring seat.When in oil circuit, oil pressure is unstable, fuel pressure acts on diaphragm, then is delivered to spring through diaphragm, and spring falls the fluctuation absorption of oil pressure, makes oil pressure become steady.At present, the most put-puts that adopt of some graden machines are as power source, as chain saw, brush cutter etc., these equipment are easy to use out of doors, saved the manual work time, and existing fuel pressure balace weight is while being used on put-put, there is following technological deficiency: structure is more complicated, processing cost is high, takes up room large, is not suitable for using on put-put.
Model utility content
In order to overcome existing fuel pressure balancer structure complexity and the large deficiency that takes up room, the utility model provides a kind of fuel pressure balace weight, simple in structure, the feature little and that be convenient to process that takes up room that this fuel pressure balace weight has, is adapted at using on put-put.
The technical solution of the utility model is: a kind of fuel pressure balace weight comprises plastic casing, the lower end of plastic casing is provided with interface, plastic casing is that cylinder funnel-like and its top are connected with plastic end cover, in the top inner chamber of plastic casing, be provided with plastic piston, between described plastic piston and plastic end cover, be provided with spring, on the corresponding surface of plastic piston and plastic end cover, be respectively equipped with the first boss and the second boss, the two ends of spring are connected to respectively on the first boss and the second boss.
Between described plastic end cover and plastic casing for being threaded.
Described plastic end cover is provided with vent.
Described interface outer wall is provided with gingival cyst of mucous gland in the newborn button.
The utlity model has following beneficial effect: owing to taking such scheme, adding man-hour, plastic casing, plastic end cover and plastic piston are by injection moulding once-through, and volume can design very little, easy to process, in use, by interface together with pipeline road in, the pressure that fluid in oil circuit produces changes vibrates plastic piston, and then change into the double vibrations of spring, play voltage stabilizing and Noise Reduction, compare with background technique, simplify the structure, take up room little, easy to process, cost is low, be adapted at using on put-put.
Accompanying drawing explanation
Accompanying drawing 1 is structure sectional view of the present utility model.
1-plastic casing in figure, 2-interface, 3-plastic end cover, 4-plastic piston, 5-spring, 6-the first boss, 7-the second boss, 8-vent.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of fuel pressure balace weight comprises plastic casing 1, the lower end of plastic casing 1 is provided with interface 2, plastic casing 1 is that cylinder funnel-like and its top are connected with plastic end cover 3, in the top inner chamber of plastic casing 1, be provided with plastic piston 4, between described plastic piston 4 and plastic end cover 3, be provided with spring 5, be respectively equipped with the first boss 6 and the second boss 7 on the corresponding surface of plastic piston 4 and plastic end cover 3, the two ends of spring 5 are connected to respectively on the first boss 6 and the second boss 7.Owing to taking such scheme, adding man-hour, plastic casing 1, plastic end cover 3 and plastic piston 4 are by injection moulding once-through, and volume can design very little, easy to process, in use, by interface 2 together with pipeline road in, the pressure that fluid in oil circuit produces changes vibrates plastic piston 4, and then change into the double vibrations of spring 5, play voltage stabilizing and Noise Reduction, compare with background technique, simplify the structure, take up room little, easy to process, cost is low, is adapted at using on put-put.
Between described plastic end cover 3 and plastic casing 1 for being threaded.The present embodiment is optimal way, can certainly adopt other Placements such as clamping.
Described plastic end cover 3 is provided with vent 8.Vent 8 makes the spring chamber of plastic casing 1 communicate with ambient atmosphere.
Described interface 2 outer walls are provided with gingival cyst of mucous gland in the newborn button.During installation, easy to connect, solid and reliable.
Claims (4)
