Abstract: A ventilation system for a crankcase for the transport of blow-by gases from the crankcase to the intake section of an internal combustion engine with supercharger. A ventilation line reaches from the crankcase to the segment of the intake section between the supercharger and the air inlet valve. An air-oil separator is arranged in the ventilation line, as well as a return line for the return of oil separated in the air-oil separator via a tank and a tank outlet valve into the crankcase. An actuating element is arranged in or at the tank. The actuating element is charged with the pressure in the intake line behind the supercharger as working pressure and which upon sufficiently high pressure transports the oil present in the tank via the tank outlet valve into the crankcase.

Abstract: A liquid separator for separating liquids from gases, having a pressure chamber and a suction chamber which are disposed in the gasflow in front of or behind a separation element is provided. The separator also may have a first siphon disposed in the suction chamber for drainage of the separated liquid, and a second siphon being disposed in the suction chamber, the barrier pressure of which is higher than the barrier pressure of the first siphon.

Abstract: The present invention relates to a fluid separation device (10) for separating fluid, oil and oil spray from a gas. This fluid separation device (10) comprises a base carrier (21) in which fluid separator elements (20) in the form of flow-through tubes with worm-like segments (23) arranged therein, are integrated. The worm-like segments (23) at the same time form spiral flow paths (25) for the gas. They have a maximal length of half a pitch of the worm-like segment (23) so that the base carrier (21) together with the associated fluid separator elements (20) may be formed as one piece. Several base carriers may be arranged one after the other in a manner such that individual fluid separator elements of various base carriers form a common flow path for the gas.

Abstract: The present invention relates to a cylinder head cover for covering a cylinder head of a combustion engine. Such cylinder head covers often comprise an oil separator for separating oil and/or oil spray from the blow-by gas of combustion engines. With the present invention the oil separator is formed as a flow-through tube (10) through which the gas with the oil and/or oil spray to be separated flows. The flow-through tube (10) with its longitudinal axis (14) in the flow-through direction lies essentially in the plane of extension of the cylinder head cover (1). A worm-like segment is arranged in the flow-through tube (10), and its thread surfaces (21) form a spiral flow path (2). At the same time the cross section of the flow path lies between 1 mm2 and 800 mm2.

Abstract: An oil mist separator has a pressure regulator valve which is located in the blow-by line downstream of the oil mist separator element in the flow direction of the gas. The pressure regulator valve has a bias so that it opens above a specified pressure difference between the blow-by line and a neighboring chamber. Located around the oil mist separator element is a bypass line which has a bypass valve. The bypass valve has a bias that causes the bypass valve to close below a specified pressure difference between the suction side and the pressure side of the oil mist separation element. The pressure regulator valve and the bypass valve are connected with each other so that the pressure regulator valve, as it closes, increases the bias of the bypass valve.

Abstract: An oil separator element of the type that is used, for example, for the separation of oil from blow-by gases in internal combustion engines is disclosed. The oil separator element has a housing which forms a cavity through which the gas can flow. The housing has an interface which divides the oil separator element into two element halves. Each of the element halves has a groove family in the interface. The grooves of the two families thereby run at an angle to one another in the interface and at least some of the grooves intersect one another. In an oil separator element of this type, the air flowing through is set in rotational motion so that both on account of the centrifugal forces that occur as well as the impact of the oil mist or the oil droplets that are contained in the gas that is carrying the oil, these oil droplets or oil mist are separated on the walls of the grooves.

Abstract: A separator for separating liquid components, in particular oil components, from a gas flow is disclosed including a cyclone and a tank. The liquid separator has a cyclone 1 with a separating chamber 2 including gas supply 3 and gas discharge 4 and a tank 5 which is connected to the cyclone 1 via a connection opening 6. The interior of the tank 5 is filled at least partially with a porous open-pore material 7 in order to interrupt the flow, dampen the flow, dampen the oscillations and/or discharge the liquid.
