Definitions

  • the present invention relates to a refueling fitting for filling vehicle gas tanks, comprising an inlet valve fluidly arranged between an inlet and an outlet, which is arranged in an elongated housing on which an actuating lever is pivotally mounted and connected via a mechanism to the inlet valve.
  • Such a refueling fitting is known inter alia from the utility model DE 203 05 357.
  • Natural gas powered vehicles are enjoying increasing popularity due to the rise in crude oil prices. In addition, they are also preferable in terms of their environmental behavior with liquid fuels powered vehicles, since they emit hardly fine dust. Nevertheless, there are problems of acceptance among consumers, since they are u. a. the handling of the associated refueling fittings feel too cumbersome. In the design of refueling valves for filling vehicle gas tanks, special attention must therefore be given to ergonomics. The valve must be light and easy to handle. It goes without saying that high safety requirements must be met.
  • a refueling fitting comprises two essential assemblies. On the one hand, this is an outlet-side quick-connect coupling for connecting the refueling fitting to the connection nipple of the vehicle gas tank.
  • the valve assembly In the second assembly is the valve assembly whose function is to keep the gas supply to the gas station closed until the refueling fitting is securely connected to the nipple of the vehicle tank.
  • the valve arrangement in turn comprises two independent valves connected in series, namely an outlet valve and an inlet valve.
  • the exhaust valve is coupled to the quick connect coupling and closes the outlet of the refueling fitting as long as the quick connect coupling is not connected to the nipple of the vehicle tank. The exhaust valve thus prevents in the last instance the outflow of the gas when the quick-connect coupling does not engage.
  • the inlet valve is arranged between outlet valve and gas supply line. It can take three switching positions, namely a venting position, blocking position and a flow position. In the venting position, the refueling fitting is vented immediately after refueling. In the blocking position, the flow through the refueling fitting is completely blocked. In the flow position, a connection between outlet and inlet is ensured, so that the tank can be filled. The user can switch the three valve positions so that he can determine the filling quantity to be tanked.
  • the present invention therefore has the object, a refueling fitting of the type mentioned in such a way that it is cheaper to produce and without the use of (pneumatic) external energy is easily switchable.
  • a refueling fitting of the type mentioned above which is characterized in that the mechanism is designed such that it converts the pivotal movements of the actuating lever in linear movements transversely, in particular perpendicular, to the housing longitudinal direction, wherein the linear movements are transmitted to the inlet valve ,
  • This type of implementation of the pivoting movements of the actuating lever in linear movement of the inlet valve transversely, in particular perpendicular, to the housing longitudinal direction of the refueling fitting has the advantage that for this purpose a very simple ausgestalteter transmission mechanism can be used, which has a favorable effect on the cost of the refueling fitting and at the same time providing a very sturdy trained and easy to handle refueling fitting allows.
  • the inlet valve comprises a piston which is axially movable in the elongated housing and a plunger, which is also axially movable, which extends at least partially in the piston.
  • the different switching positions of the intake valve are realized by different positions of the piston to the housing or the plunger relative to the piston.
  • plunger and piston are designed so that when switching from the venting position to the blocking position, only the plunger is initially moved relative to the piston. During the subsequent switching from the blocking position to the flow position, the plunger takes the piston so that they move together relative to the housing.
  • the axially movable valve components Pistons and plungers move linearly within the housing.
  • a linear actuation movement is ergonomically unfavorable.
  • a pivotally mounted in the housing actuating lever is provided according to the invention, which executes a rotational actuation movement as in conventional gasoline fuel nozzles.
  • the angular movement of the actuating lever relative to the housing is transmitted by means of the mechanism to the inlet valve, in particular its plunger, whereby the angular movement of the actuating lever is converted into a linear movement of the plunger.
  • the mechanism is according to an expedient embodiment of the invention to a single coupling, which is mounted on the one hand with a hinge in the operating lever and on the other hand with a rotary joint in the plunger.
  • Actuator lever, coupling, ram and housing then together form a slider crank gear.
  • the mechanism may also take other, multi-membered forms, which are suitable to convert the angular movement of the actuating lever in a linear movement of the plunger. It would be conceivable z. B. also a roller which is rotatably mounted in the plunger and rolls on the operating lever. The mechanism would then be based on a cam gear. Also conceivable is a multi-link mechanism made of articulated links to possibly achieve a better gear ratio.
  • the refueling fitting according to the invention impresses with its simple mechanical construction.
  • the intake valve can be switched without auxiliary power via an actuating lever whose movement behavior corresponds to that of conventional gasoline fuel nozzles.
  • the refueling fitting can therefore be operated in a manner similar to a conventional gasoline nozzle.
  • Plunger and piston of the coaxial inlet valve are preferably designed as described in the features of the subclaims.
  • the associated piston stops are in the housing.
  • the plunger strikes against a second plunger stop of the piston to this in the switching movement of the Take blocking position into the flow position.
  • the second plunger stopper is to be arranged on the piston.
  • the first plunger stop can optionally be arranged on the housing or on the piston, since the first plunger stop, unlike the other stops, is not absolutely necessary for determining a switching position.
  • the plunger is not permanently in the venting position on the first plunger stop, but moves between the first and second plunger stop to give the inlet valve a dead path.
  • Springs press piston and plunger against their first stop, so that the unactuated valve is in any case in the vent position.
  • the actuating lever is not actuated, the gas supply line is then already blocked by the inlet valve.
  • the sealing surface of the housing is identical to the first piston stop, or that the second plunger stopper is identical to the inner sealing edge of the piston. In this way, it is ensured that the force transmission between the piston and the housing, or between plunger and piston always takes place via the sealing edge and thus a correspondingly high contact pressure acts on the sealing element.
  • This solution is especially hard seals. However, if a soft seal is provided, it is advisable to functionally separate the seal and stop.
  • the plunger it is expedient to guide the plunger in the housing. This ensures that the lateral guiding forces are applied by the stationary housing and not by the piston, which in turn is movable. In this way, the seals and guides of ram and piston are less stressed.
  • the piston spring between the piston and housing is tensioned. In this way, an immediate load of the piston takes place.
  • the plunger spring which is to be arranged between plunger and piston.
  • the springs could each be arranged between the actuating lever and the housing. However, this is not appropriate, since then the spring force would have to be transmitted via the coupling.
  • the spring stiffness of the plunger spring is preferably less to choose than the spring stiffness of the piston spring. This has the consequence that the force required to switch the valve from the vent position to the blocking position is less than the force required to shift from the blocking position to the flow position - provided that the stroke of plunger and piston is approximately equal. A malfunction of the refueling fitting is counteracted. More important, however, is that the piston is loaded in the flow position by a high spring force, which is able to overcome any gas-dynamic forces acting on the piston. A safe closing of the valve is thereby ensured.
  • the said gas dynamic forces should be reduced by the fact that the flow around surfaces of plunger and piston are dimensioned so that any pressure differences do not result in longitudinal forces that adversely affect the switching behavior of the valve.
  • the aim is to load plunger and piston in each switching position only by spring force and manual operating force.
  • piston and plunger are arranged transversely to the flow direction of the refueling fitting. This gives the refueling fitting a particularly compact design.
