Definitions
- the invention relates to a pressure control valve with a pressurized membrane for closing and opening a gas passage according to the preamble of the main claim.
- a pressure control valve is switched in an intake path for the internal combustion engine.
- this pressure control valve is also in a Vent line between the crankcase and the intake pipe or the air filter or in the ventilation line of the fuel tank in a motor vehicle two flanges installed. In any case, it is about the pressure or negative pressure in the units to be vented do not rise above a predetermined value allow.
- a membrane is available for this purpose, e.g. against the force of a valve spring the passage through the Controls opening of a channel and closes if necessary.
- the invention has for its object a pressure control valve according to the preamble of the main claim to simple Way so that a space-saving attachment is possible without much effort.
- the pressure control valve according to the invention with a pressurized Membrane for closing and opening a Gas passage according to the type specified at the outset, triggers the task set with those in the characterizing part of the main claim specified features. It is advantageous the pressure control valve is arranged so that the outlet of the Gas passage directly in a room with ambient pressure, usually with atmospheric pressure.
- the membrane is a ventilation hole, e.g. there is a hole through the one on the one to be closed and opened Gas passage opposite side of the membrane existing valve chamber directly with the ambient pressure can be applied.
- the membrane is preferably in the valve chamber Lock under the pressure of a coil spring against the Gas passage opening pressed.
- Pressure regulating valve is easily arranged for venting a crankshaft housing in the intake tract of an internal combustion engine can be used. It is here advantageous that the pressure control valve saves space without Consideration of ventilation channels directly in a pressure body can be integrated as an additional introduction of hoses or channels.
- An embodiment of the pressure control valve according to the invention with a pressurized membrane to close and opening a gas passage in a vent assembly for a crankcase in one Motor vehicle is based on the sectional view of the single figure of the drawing explained.
- the figure shows an arrangement with a pressure control valve 1 shown that has the task in practical operation that through that into a vent line between the intake manifold and the crankcase one not shown here Internal pressure control valve 1 Blow-by gas is drawn through in the direction of arrow 2.
- a gas inlet 3 is connected to the crankcase and is on a distributor plate 4, or on a fleece wrap, distributed.
- a membrane 5 under the pressure of an applied to the housing of a valve chamber 8
- Coil spring 6 on a closable with the membrane 5
- Opening 7 is pressed as a gas passage.
- the opening 7 leads into a room with an ambient pressure Pu, usually with atmospheric pressure.
