Definitions
- the present invention relates to a control valve for automatic air brakes for forming a brake cylinder pressure C in at least one connected brake cylinder in accordance with a pressure difference between a pressure in a continuous main air line L of a train and a stored reference pressure A, which is derived from the pressure of the main air line L, comprising valve means for deriving a control pressure S from the pressure of the main air line L for generating a brake cylinder pressure C for the application of the brake cylinder, comprising a first valve mechanism for providing the control pressure S from the pressure of the main air line and a second valve mechanism for generating the brake cylinder pressure C.
- Rail vehicles usually have an automatic automatic air brake, in which the lowering of the pressure in a main air line L, starting from a control operating pressure causes the formation of a brake cylinder pressure C.
- the transfer function of decreasing pressure in the main air line L to the increasing brake cylinder pressure C and vice versa is performed by the control valves of the type of interest here.
- control valve consists of two separate parts, which are usually mounted on a common valve carrier, whereby the necessary compressed air connections are made with the relevant connections to the valve carrier. Inside the valve carrier there are chambers for a control pressure
- the control valve consists here of a main part and a line part.
- the generation of the brake cylinder pressure C is the main part, while the line part generates the control pressure S and includes a signal amplification accelerator.
- Both pressures, A and S are used to control the main part, wherein the pressure A when applying the brake, the reference to the control operating pressure, ie the original pressure in the main air line L in driving position, and the control pressure S, the time-corrected reference to the current pressure in the main air line L during braking.
- the main and line part of the control valve are provided with their own piston systems, which assume different positions starting from the pressure difference A to S in the main part and L to S in the line part, with defined switching positions of the respectively connected valve mechanism adjust, which realize different compressed air connections.
- the distribution of the control valve in the main and line part has the disadvantage of multiple parts associated with a higher cost for the preparation and processing of the control valve.
- SU 1629210 and SU 1712217 disclose one-piece control valves.
- Essential components of these control valves are an L-piston which is acted upon by the main air line pressure L and the reservoir pressure R, an integrated double-seat valve for loading or bleeding the connected brake cylinder and a compensating piston which is moved by the brake cylinder pressure C against the force of two adjustable compression springs. Starting from a brake signal, the pressure L decreases, wherein the pressure R is substantially maintained.
- the resulting pressure difference moves the L-piston, so that first opened a hole for filling a transmission chamber with L-air and a connection between supply air R and main air line L is closed and then opens the inlet valve and air from the reservoir air tank R flows into the brake cylinder , In consequence of the As the brake cylinder pressure C increases, the balance piston moves and closes the intake valve.
- the invention includes the technical teaching that cooperates with a one-piece control valve a sohubiges first piston system for actuating the first valve mechanism in the same valve housing with a relatively langhubigeren second piston system for actuating the second valve mechanism.
- a sensitive organ in the form of a first piston system with short strokes is used for detecting the brake signal and used for brake cylinder pressure generation an organ in the form of a second piston system with relatively longer strokes for the purpose of high performance.
- the piston stroke of the second piston system corresponds to 1.5 to 3 times the piston stroke of the first piston system. In the context of this piston stroke ratio, both a high sensitivity on the part of the valve mechanism for providing the control pressure S and the second valve mechanism for generating the brake cylinder pressure C is achieved.
- the accelerating member preferably comprises a vent valve and a spring-loaded check valve, the former being connected between the pressure of the main air line L and a vent channel with the atmosphere to bring about a gain effect for the braking at a decreasing pressure of the main air line L.
- the first piston system comprises a control piston which actuates the accelerating member via a piston rod.
- the acceleration member is preferably designed as a vent valve of the type mentioned above. This vented in the braking effecting actuated switching position, the main air line L to cause a signal amplification of the discontinued by lowering the pressure brake signal.
- the second piston system comprises a control piston associated therewith, which actuates the second valve mechanism via a piston rod.
- the second valve mechanism is preferably designed as a double seat valve. In the brake actuated actuated switching position of the double seat valve is supplied with originating from the supply air reservoir pressure R of the brake cylinder to perform the braking.
- the valve carrier provides the compressed air connections C, R, L ready for the compressed air connection of the control valve.
- the vent connections preferably lead directly from the common valve housing to the outside.
- FIG. 1 shows a schematic longitudinal section through a control valve as an actuator for a regulated pressurization of a brake cylinder.
- the control valve essentially consists of a short-stroke first piston system 3 arranged in a common valve housing 1 for actuating an associated acceleration element 2 via a piston rod 6.
- These components include the function of a so-called L-part of a control valve which is formed from the pressure of the main air line L derives the control pressure S. Furthermore, this arrangement controls at the beginning of a braking connection from the main air line L to a channel of the additional venting via the vent valve 13 in the region of the accelerating member. 2
- a second piston system 5 which has a long stroke relative to the first piston system 3, is arranged which serves to actuate the valve mechanism 7 via a piston rod 8.
- the valve housing 1 of the control valve is detachably attached to a valve carrier 14 via a flange surface.
- the valve carrier 14 provides the compressed air connections for the brake cylinder pressure C, the supply pressure R and the main air line pressure L.
- the main air line L is filled with a constant pressure.
- the pressure chamber of the control pressure S below the control piston 12 also fills with the pressure from the main air line L.
- the pressure from the main air line L is also in the pressure chamber of the reference pressure A above the control piston 16 of the second piston system 5 via the connecting channel 17 at.
- the pressure in the main air line L is reduced externally.
- the control pressure on the control piston 12 of the first piston system 3 via the connecting channel 15 of this external pressure reduction can not follow at the same time, so that adjusts an equilibrium of forces on the control piston 12.
- the control piston 12 moves in the direction of the accelerating member 2 and the venting valve 13 opens, so that a brake signal amplification is brought about, in which additionally compressed air is vented from the main air line L.
- first and / or second valve mechanism also include other valve components for influencing the generation of the brake cylinder pressure.
