Abstract: A filter insert for being removably arranged in a filter housing includes a first connection arrangement for engaging a corresponding second connection arrangement of a filter housing lid for a connection to the filter housing lid. The first connection arrangement is arranged to simultaneously prevent a relative rotational movement between the filter insert and the filter housing lid and allow a relative axial movement between the filter insert and the filter housing lid.

Abstract: A filter insert for being removably arranged in a filter housing defines a first end and a second end opposite the first end, including a closing arrangement at the first end of the filter insert for controlling opening and closing, respectively, of an aperture, and an actuation arrangement operatively connected to the closing arrangement for actuating the closing arrangement, wherein the actuation arrangement is positioned at the second end of the filter insert and wherein the actuation arrangement is accessible for external contact at the second end of the filter insert.

Abstract: A variable valve actuation mechanism is provided for an internal combustion engine including at least one valve for control of gas admission to a cylinder of the engine and/or gas exhaust from the cylinder. The mechanism includes two concentrically arranged camshafts, a cam set comprising two cams, each fixed to a respective of the camshafts, whereby the camshafts are arranged to be turned in relation to each other, so as to change the combined profile of the cams, and a cam follower adapted to follow the combined profile of the cams and to actuate at least one of the at least one valve in dependence on the combined profile of the cams, wherein the cam follower includes two rollers, each roller being adapted to follow a respective one of the cams.
