Abstract
The utility model relates to a check valve (1) for an air duct in an internal combustion engine region; the check valve comprises a housing (3) having at least one valve seat with a valve hole (2), one valve plate element (5) and one valve stopping element (6), wherein the valve plate element is a steel plate spring; the valve plate element (5) and the valve stopping element (6) are designed as an integrated valve locking device (4).
Description
Technical field
The utility model relates to a kind of safety check that is used for the air pipe in the internal-combustion engine zone, and this safety check comprises the shell with at least one valve seat that has valve opening, valve plate element and valve stop element, and wherein, the valve plate element design is a leaf spring.
Background technique
By known this a kind of safety check of DE 199 53 198 A1.This safety check especially uses in the waste gas circulation zone, and wherein, the pressure in the pressurized air conduit can and should stop pressurized air to flow in the waste gas circulation conduit greater than the pressure in the waste gas circulation conduit.Though part count is less, especially the assembly fee in multidirectional safety check is very high.
Summary of the invention
Therefore, the utility model technical problem to be solved is to obtain obvious still less assembly fee usefulness of a kind of needs and correspondingly more cheap during fabrication safety check.
This technical problem solves through a kind of safety check by the utility model type like this, and the block of valve that makes valve plate element and valve stop element be designed to integral type tightly installs.In such a way, guarantee the simple especially and therefore assembling at an easy rate of safety check.Proved that especially favourable is that the tight device of the block of valve is designed to sheet metal bending part.At this, the tight device of the block of valve can have elastomer coating.Remove in addition, but the valve seat area of shell also can have the elastomer coating of thermal load at least, to guarantee sealing well in closed state.In order further to simplify assembling, shell has clip slot, and the block of valve is bearing in this clip slot with tightly installing form fit ground and frictional fit.Remove in addition, also can realize, the tight device of the block of valve for example is connected with shell through rivet, thread connecting mode etc. through valve stop element frictional fit ground.In this case, especially advantageously, shell has connecting pin.
Shell also can have around seal arrangement, the sealing device guarantees the sealing effect between air pipe and the safety check on the one hand, is arranged in the conduit of air guide with guaranteeing the safety check damping on the other hand.Shell also possibly have a plurality of valve openings.
Description of drawings
A kind of form of implementation of shown in the drawings and following description the utility model.In the accompanying drawings:
Fig. 1 is the stereogram of multidirectional safety check,
Fig. 2 is the side view of safety check among Fig. 1.
Embodiment
Fig. 1 is the stereogram by safety check 1 of the present invention, and this safety check 1 is designed to multidirectional safety check, that is to say that design has four valve openings 2.Safety check 1 is installed in the waste gas circulation conduit not shown further in this form of implementation and should guarantees, when charge-air pressure sealing waste gas circulation conduit rapidly during greater than average exhaust gas pressure, gets in the waste gas circulation conduit to stop pressurized air.For this reason, if expectation is such, the certain and independent pressurized air conduit acting in conjunction of independent waste gas circulation conduit.
Safety check by the utility model has shell 3, and this shell 3 has four valve openings 2 that form valve seat respectively in this form of implementation.These valve openings 2 can be by tight device 4 sealings of the block of valve.The tight device of the block of valve 4 is designed to sheet metal bending part by the utility model, and both has been included in the valve plate element 5 that charge-air pressure can seal each valve opening 2 when too high, also comprises the valve stop element 6 that limits 5 deflections of valve plate element.The tight device of the block of valve 4 is bearing in the clip slot 8 through transition zone 7, is connected to connecting pin 10 frictional fit through screw 9 and shell 3 in addition.Now in order to reach safety check 1 good sealing effect between waste gas circulation conduit and shell 3, and in addition, be bearing in the waste gas circulation conduit to shell 3 dampings, setting around seal arrangement 11.Remove in addition, shell 3 is for example processed by aluminium or thermosetting plastic, and wherein, but valve seat area is with the elastomer coating of thermal load, to guarantee best sealing.
Fig. 2 illustrates the sectional drawing by safety check 1 of the present invention again at this.Most clearly see, be fixed in the connecting pin 10 through screw 9 at the tight device of this block of valve 4.Here, safety check 1 is positioned at the position of opening, that is, valve plate element 5 is moved away from valve opening 2 and the valve seat that is attached thereto and clinged to the position on the stop element 6.
