Abstract
The utility model discloses an automatic inflating air valve which is suitable for the inner tubes of various vehicles. The automatic inflating air valve comprises an inflating valve, a push rod, an air pump, a dust-proof cap, a sealing ring, etc. The automatic inflating air valve organically combines the inflating valve and the pump together. In a running process, the automatic inflating air valve utilizes pressure received by a tyre to push a piston to cause an inner tube to automatically inflate. When tyre load is changed, the automatic inflating air valve can automatically regulate the air pressure of the inner tyre to cause the air pressure of the inner tyre to be maintained within a suitable range, and the air pressure range is matched with the load. The automatic inflating air valve is a unified integral body, has small size and simple manufacturing technique.
Description
It belongs to transportation class.
Be used for the valve and the automatic air inlet of vehicle tyre at present, mainly contain:
(1) English valve: it is made up of tire tube valve, valve inside, small rubber pipe, nut etc.
(2) American valve: it is made up of tire tube valve, valve inside etc.
More than two kinds of valves must be equipped with air pumps or utilize and manually inflate.
(3) the automatic air intake device of bicycle: it is by being attached near the axletree air pump under the drive of gear or cam, promoting piston air is pressed into above-mentioned valve through tubule.Its volume is big, and complex structure needs increasing energy consumption, and fragile.
The objective of the invention is to make the inflation automatically in the process of moving of a kind of vehicle, the continuous automatically regulating of air pressure keeps within the specific limits in making.Save energy consumption.
Automatically charging valve is made up of tire tube valve (1), push rod (2), air pump (it by pump at the bottom of double-screw bolt (3), air pump housing (4), pressure spring (6), piston (7), pull back spring (8), air outlet valve (9), air inlet valve (10), pad (12) constitute), dust cap (11), seal ring (5).Wherein air pump directly links to each other with tire tube valve (1).Tire tube valve (1) endoporus is equipped with push rod (2), and the transmission between piston (7) and the push rod (2) is made up of pressure spring (6) and pad (12).Dust cap (11) is housed at the top of air pump, and it is made of plastics, and the bigger filtering membrane of one deck order number is housed in it, and impurity screening keeps excellent air permeability.The material of whole valve is metal and engineering plastics.
The invention has the advantages that whole valve is unified integral body, volume is small and exquisite, and is in light weight, and manufacturing process is simple, does not need additional equipment, utilizes gravity acting, and energy consumption is few, and is durable in use, uses extensively, and low price is suitable for bike tyre especially.
Figure is a cutaway view.According to figure, the pump that an end is segment shape garden capital bar (2), air pump is housed in tire tube valve (1) endoporus at the bottom of double-screw bolt (3) endoporus screw thread is arranged, with tire tube valve (1) direct connection, and with seal ring (5) sealing, push rod (2) can slide within it.Pull back spring (8) is enclosed within on the piston (7), is installed in the air pump housing (4), and the activity that seals or be processed into good seal between the gentle pump case of piston (7) (4) with seal ring cooperates.Drive mechanism between piston (7) and the push rod (2) is made up of pressure spring (6) and pad (12), and double-screw bolt at the bottom of the pump (3) is tightly connected with air pump housing (4) and is integral, and constitutes the air pump shell.Piston (7) endoporus is equipped with air outlet valve (9), and air inlet valve (10) is housed in the induction opening of air pump top, and at the air pump top dust cap (11) is housed.When vehicle ', ground is in the face of the tire compression, push rod (2) is slided in double-screw bolt (3) at the bottom of tire tube valve (1), the pump, promote pad (12), pressure spring (6), piston (7), compression retracteding position spring (8), make the pump chamber pressure rises to the interior pressure greater than air outlet valve (9), the gap of air between push rod (2) and tire tube valve (1) enters the inner tube of a tyre; The ground compression is eliminated, and pull back spring (8) promotion piston (7) makes and occurs negative pressure in the pump chamber, and air enters pump chamber through dust cap (11), air inlet valve (10).After load minimizing or the raising of tire internal gas pressure, push rod (2) promotes piston (7) stroke to be reduced, and pump chamber air pressure improves inadequately, can not back down air outlet valve (9), and air no longer enters the inner tube of a tyre.When the tire internal gas pressure reduces or loads when excessive, push rod (2) stroke is greater than piston (7) stroke, and pressure spring (6) plays the effect of the buffer protection inner tube of a tyre and air pump.
Claims (3)
1, a kind of automatic charging valve it form by tire tube valve (1), push rod (2), air pump (constituting), dust cap (11), seal ring (5) etc. by double-screw bolt at the bottom of the pump (3), air pump housing (4), pressure spring (6), piston (7), pull back spring (8), air outlet valve (9), air inlet valve (10), pad (12), it is characterized in that air pump directly links to each other with tire tube valve (1), tire tube valve (1) endoporus is equipped with push rod (2).
2, it is characterized in that according to the automatic charging valve of claim 1 transmission between piston (7) and the push rod (2) is made up of pressure spring (6) and pad (12).
3, the automatic charging valve according to claim 1 is characterized in that the air pump top by dust cap (11) is housed, and it is made of plastics, and the bigger filtering membrane of order number is housed in it.
