  • Publication number: 20180036667
    Abstract: A secondary element with a first open end and a second end positioned opposite the first end has a filter medium arranged about a longitudinal axis of the secondary element and extending from the first open end to the second end. A closed end disc is disposed at the second end and seal-tightly closes off the second end. The closed end disc has a first connecting element that, for an intended installation of the secondary element in a filter system, is configured to interact with a second connecting element of a support tube of the filter system to secure the secondary element on the support tube. A filter system with such a secondary element has a support tube provided with a complementary second connecting element, wherein the secondary element is secured on the support tube by the first and second connecting elements engaging each other.

  • Publication number: 20160280045
    Abstract: A cabin air filter is provided with a filter medium and a filter element frame that frames the filter medium and is configured to attach the cabin air filter to a filter housing. The filter element frame is provided with at least one engagement element configured to engage pivotably at least one receiving element of the filter housing for pivoting the cabin air filter relative to the filter housing about a pivot axis. The filter element frame also has at least one snap hook that locks with at least one locking element of the filter housing for blocking pivoting of the cabin air filter relative to the filter housing at least in a first direction about the pivot axis.

  • Patent number: 7938872
    Abstract: The invention concerns a separating device for separating particles (4) from a gas stream (2) in which the gas stream (2) by means of a guiding device is caused to rotate and the liquid or solid particles (4) to be separated are removable by a particle outlet. The separating device (1) is comprised of a cylindrical housing pipe (5) with a guiding device (3) and an immersion pipe (6) arranged in alignment with the flow direction of the gas stream (2) in the housing pipe (5) which immersion pipe is provided on the exterior with a spiral (7) for a directed removal of the particles (4) separated by rotation to a housing opening (8) and with a central outlet (9) for the purified gas stream (2).

  • Patent number: 5611606
    Abstract: A brake-pressure control device for a hydraulic multi-circuit brake system provides for brake-pressure generation, in addition to a brake unit, hydraulic regulating cylinders with electromotively drivable pistons. By electronic activation of the cylinders, the wheel brakes can be activated even without the cooperation of the driver. In the regulating cylinders of the front-wheel brakes, the pistons have a basic position, out of which brake-pressure build-up and reduction strokes can be executed. The pistons of the regulating cylinders of the rear-wheel brakes have a basic position which corresponds to the largest volume of the outlet-pressure spaces. The regulating cylinders are equipped with electronic position transmitters. A sensor whose output signal measures the expected value of the vehicle deceleration with which the driver wishes to brake is also provided.
