Definitions
- Ventilation device for a hydraulic system
- the invention relates to a venting device for a hydraulic system, which comprises at least a slave cylinder with a pressure medium inlet, a master cylinder with a Druckschauslass and provided with at least one connection element / connector pressure medium line having a pressure medium inlet hydraulically operatively connected to the Druckstoffauslass fluid channel.
- venting devices for hydraulic systems have a separate, connected to the pressure medium line, housing in which axially a plug - with or without thread - is rotatably arranged.
- the plug forms with the housing via incorporated sealing surfaces an axial sealing seat and thereby sealingly seals the pressure medium line.
- the sealing seat is separated by, for example, the plug is loosened by a rotary motion, which is discharged through an opening in the plug from the system to be removed air and possibly excess pressure medium.
- a variety of known applications also provides an arrangement of the venting device either directly to a hydraulic component, eg. B. on a semi-hydraulic slave cylinder or on a Monausgurer ago. Often also the hydraulic component associated adapter pieces are used.
- a vent valve disclosed in DE 10 201 1085 649 A1 has a T-shaped housing which is inserted into the pressure line between two ends.
- the housing consists of an upper and a lower shell-shaped housing part, which surround the pressure line and are connected to one another via connecting elements.
- the upper housing part is designed to form a T with a projection in the form of a socket which receives the provided with a vent passage plug.
- the known ventilation devices also require in addition to a relatively large number of components and an additional space.
- their use is largely limited only to the specific hydraulic system or the specific hydraulic component.
- the object of the invention is therefore to propose a cost-effective venting device for a hydraulic system, which is easy to handle in a compact design and few components and is universally applicable.
- a venting device for a hydraulic system which at least comprises a slave cylinder with a pressure medium inlet, a master cylinder with a Druckmit- telauslass and provided with at least one connection element / connector pressure medium line having a pressure medium inlet hydraulically operatively connected to the Druckstoffauslass fluid channel, characterized in that the venting device is integrated in the connecting element / connector.
- connection element / the connector has a receiving bore corresponding to the fluid channel, in which a venting plug is rotatably arranged about its longitudinal axis and can be brought from a closed to an open position and vice versa.
- a rotary movement of the vent stopper about its longitudinal axis / rotation axis is limited to an angle of 180 °.
- a vent hole is provided, which is arranged approximately orthogonal to the vent plug accommodating receiving bore, wherein the vent hole before its entrance into the receiving bore preferably merges into a provided with a reduced cross-sectional area vent passage.
- the venting bore is located in a venting nipple arranged on the connection element / connector.
- At least one sealing element is provided between the vent plug and the wall of the receiving bore, which is arranged in a plane inclined to the longitudinal axis of the vent plug, wherein depending on the rotational position / position of the vent plug a connection between an approximately orthogonal to the receiving bore, the fluid channel receiving, through-flow bore of the connection element / connector and the venting bore / the venting channel is or is interrupted.
- the sealing element is in this case preferably designed as an O-ring and arranged on the vent plug in a complementary, obliquely extending to the longitudinal axis, annular groove.
- the venting plug and the connector can furthermore be connected to one another by means of a snap connection which realizes an axial fixation of the venting plug.
- snap hooks are arranged on a located outside of the receiving bore of the connector head piece of the vent plug, which can be brought into engagement with arranged on the connector latching lugs.
- Fig. 1 is a sectional view of the venting device according to the invention in one
- Fig. 2 is a sectional view of the venting device according to the invention in one
- FIG. 3 is a front and a side view of the venting device according to the invention. 1 and FIG. 2 respectively show the venting device 1 according to the invention in a sectional view along a line AA according to FIG. 3. In this case, FIG. 1 shows a closed and in FIG. 2 an opened state of the venting device 1.
- the venting device 1 is part of a hydraulic system, preferably a clutch release system of a motor vehicle, whose operation is known per se.
- the hydraulic system comprises a pressure medium line 2 (shown in Fig. 3) with a fluid channel 2.1 for pressurizing individual hydraulic components, such as a not shown in detail slave cylinder of the clutch release system.
- a connection element 3 designed here as a connector, on.
- the connector 3 has a housing with a receiving bore 3.1, in a the
- Fluid channel 2.1 receiving flow hole 3.2 opens.
- a vent stopper 4 which is arranged rotatably about its longitudinal axis L.
- a located outside of the connector 3 head piece 4.1 of the vent stopper 4 has on its outer periphery snap hooks 4.2, which are arranged with the outer circumference of the connector 3, complementarily formed, locking lugs 3.3 are engageable.
- the snap hooks 4.2 of the head piece 4.1 engage around the latching lugs 3.3 having part of the connector 3 to form a snap connection.
- the vent stopper 4 is fixed in the direction of its longitudinal axis L.
- vent hole 3.4 is also provided, which extends approximately orthogonal to the vent plug 4 receiving bore 3.1 and opens into the latter.
- the vent hole 3.4 has at its confluence with the receiving bore 3.1 on a greatly reduced cross-sectional area owning vent channel 3.5.
- the vent hole 3.4 is located with the vent channel 3.5 in a arranged on the connector 3 bleed nipple 3.6.
- sealing element 5 is provided between the vent plug 4 and the wall of the receiving bore 3.1 of the connector 3 , which is arranged in one to the longitudinal axis L - which is also the axis of rotation - the vent plug 4 inclined plane is.
- the sealing element 5 is in this case in a on the circumference of the vent plug 4 introduced, complementarily shaped, oblique annular groove 4.4 and is thereby fixed to the vent stopper 4.
- the O Ring trained sealing element 5 would be, for example, an oblique, with the vent stopper 4 co-rotating, hose rubber used.
- the sealing element 5 is located between the flow-through 3.2 and the venting channel 3.5 on the wall of the receiving bore 3.1 and thus prevents bleeding of the hydraulic system.
- FIG. 2 shows the opened position of the venting device 1.
- the diameter of the receiving bore 3.1 of the connector 3 can be kept relatively small With the resulting reduction of the hydraulic plug acting on the venting plug 4 (for example by about 75%)
- the actuating moment necessary for opening the vent stopper 4 under pressure also decreases, thus making it possible to depressurize the vent stopper 4 under pressure with a simplified operation.
- Fig. 3 is a front view and a side view of the venting device 1 according to the invention are shown. This is particularly evident in their compact design. With the provided with an N arrow of the connection to the slave cylinder, not shown, is indicated.
- venting device 1 By installing the venting device 1 in the already existing in the hydraulic system connection element (connector 3) to obtain a universally applicable - in the described embodiment of all slave cylinder matching - vent 1.
- the connector 3 with the integrated venting device 1 fits all housings and adapters.
- the arrangement of the vent hole 3.4 / the venting nipple 3.6 on the connector 3 also supports a compact design of the venting device. 1 Reference list. vent
