A camshaft may include a support shaft and a component with a passage opening that receives the support shaft. The support shaft may include fastening regions and positioning regions alternating in an axial direction. A diameter of the support shaft in the fastening regions may be greater than a diameter of the support shaft in the positioning regions. Furthermore, the passage opening of the component may include axially spaced fastening sections with positioning sections arranged between pairs of the fastening sections. A diameter of the passage opening in the fastening sections may be smaller than a diameter of the passage opening in the positioning sections. Further, the diameter of the support shaft in the positioning regions may be smaller than the diameter of the passage opening in the fastening sections, and the diameter of the support shaft in the fastening regions may be smaller than the diameter of the passage opening in the positioning sections.

A rotary electromagnetic actuator includes a biasing assembly for applying a torque to its rotor. Such an actuator may be used to operate a poppet valve of an internal combustion engine. The rotor defines a cam surface and the biasing assembly includes a cam follower in engagement with the cam surface, and the magnitude of the torque exerted on the rotor by the biasing assembly is dependent on the magnitude of the displacement of the cam follower by the cam surface. The cam surface defines at least one detent for receiving the cam follower.

A plunger pump having improved durability without leading to a reduction in productivity is provided. A pump apparatus includes a sliding portion provided between a stopper portion and an eccentric cam in a direction of an eccentric central axis and having a lower frictional coefficient between the sliding portion and the eccentric cam than a frictional coefficient between the stopper portion and the eccentric cam.

A pair of spaced-apart cam disks disposed along a common power shaft, with a pair of cam followers disposed within channels formed in opposing inner surfaces of the cam disks, forms a balanced arrangement for creating linear reciprocating motion from the rotation of the pair of cam disks. A linear motion shaft is coupled to the cam followers. As the cam disks synchronously rotate and the cam followers trace the path formed by the paired channels, this rotational motion is converted into linear, reciprocal motion that provides the translational movement of the linear motion shaft.

Engine and its camshaft, camshaft manufacturing method, the camshaft comprises a central shaft having an axial hole, the central shaft has a fitting section, the outer circumference of a cross section at any axial position of the fitting section is a polygon; a first cam and a second cam, the first cam and second cam are respectively installed on the fitting section of the central shaft and are spaced axially. Such a structure has the advantages of higher torque transmission, simpler structure, simplified manufacturing process, shorter manufacturing time consumption and reduced cost.

A sliding module having a sliding sleeve and at least one cam segment having at least one cam. The sliding sleeve has a positioning section for positioning the cam segment fixedly against rotation and displacement. The positioning section includes a surface structure on the outer circumferential face of the sliding sleeve for producing a press-fit connection between the cam segment and the sliding sleeve. A stop region is provided configured to limit an axial movement of the cam segment.

A cam liner for use in an integrated drive generator has a cam liner body extending between a first end spaced from the second end by a first distance. The body is generally cylindrical. An outer diameter of the cam liner defines a second distance. A ratio of the first distance to the second distance is between 0.90 and 1.00. An integrated drive generator and a method are also disclosed.
