A hybrid engine having a plurality of combustion power assemblies disposed about an engine driveshaft on which is mounted spaced apart cams, each combustion power assembly disposed between the cams radially outward of the driveshaft and having a combustion cylinder with a fuel injector mounted thereon and with a reciprocating piston assembly disposed in each end of the combustion cylinder. A cam follower is attached to each piston assembly and engages a respective cam. An electric power assembly may be mounted radially outward from the driveshaft and adjacent at least one cam as a radial power assembly or may be mounted along the driveshaft between the two cams as an axial power assembly.

A system for adjusting a rake of a steering column includes a rake actuator. The system also includes a jacket assembly. The system further includes a first bracket operatively coupled to the jacket assembly, the first bracket defining a first slot. The system yet further includes a second bracket defining a second slot, the second bracket fixed in a stationary position relative to the first bracket, the first and second slots oriented at different angles, but partially aligned. The system also includes a cam follower operatively coupled to the rake actuator, the cam follower having an arm extending through the first slot and the second slot, wherein translation of the cam follower adjusts the angular position of the first bracket and the jacket assembly.

The present invention uses a bearing having one radial bearing part and two axial bearing parts, each bearing part having a plurality of rolling elements retained in a retainer. The row of rolling elements of the radial bearing part contacts the outer peripheral surface of an output shaft, and the row of rolling elements of the two axial bearing parts or of one of the axial bearing parts contacts the outer peripheral surface of the output shaft and the row of rolling elements of the other axial bearing part contacts a first ring-shaped part fixed to the output shaft, so as to form an output-shaft side raceway surface. Meanwhile, the row of rolling elements of the radial bearing part and of the two axial bearing parts contacts the surface of a second ring-shaped part that is disposed on the periphery of the output shaft and that is fixed to a housing, or the row of rolling elements of the radial bearing part and of one of the axial bearing parts directly contacts the inner surface of the housing, so as to form an outer raceway surface. Due to this configuration, the bearing is rotatably supported by the housing.

A cam follower roller device having a tappet body extending along a longitudinal axis and defining a tappet bore, a pin centered on a transverse axis and providing two opposite ends arranged in through-holes transversally facing one another on tappet body, and a roller rotatably mounted on the pin around said transverse axis. The tappet body is a machined metal tube or bar and is provided with a radial plate that is securely fixed within tappet bore, said radial plate being dedicated to support a longitudinally movable piston.

A cam mechanism for converting a swiveling movement of a drive-side shaft into a linear output movement. A cam disk is attached to the drive-side shaft, a slider is shiftable in a linear guide, and a cam follower is applied against the circumferential surface of the cam disk. Swiveling movement of the cam disk leads to a linear output movement of the slider in the linear guide. The circumference of the cam disk is spiral-shaped at least in sections, and the radius of the cam disk increases monotonically in the spiral-shaped section from a start radius to an end radius along a swiveling direction. By selecting two reversal points within the spiral-shaped section, the setting of a variable stroke can occur. A piston pump is provided with the cam mechanism and a method is provided for using the cam mechanism and the piston pump.

In embodiments, a mechanical solar tracker for energy and shade disclosed herein includes a positioning cam comprising one or more paths being configured as a function of a latitude location of the mechanical solar tracker; a sleeve coupled to an adjustment arm, the adjustment arm operable to rotate the sleeve about a vertical axis; a cam follower coupled to the sleeve, the cam follower configured to translate a selected path of the one or more paths as the sleeve rotates about the vertical axis, and a surface coupled to the cam follower. In embodiments, the selected path is configured such that as the sleeve rotates about the vertical axis, the cam follower maintains the surface normal to a vector defined by an azimuth angle and elevation angle, wherein the azimuth angle may be the sun azimuth angle and the elevation angle may be the sun elevation angle.
