LINEAR ELECTRIC DEVICE

An electric device has a driveshaft with at least one stator cylinder positioned between opposing, curvilinear shaped cams mounted on the driveshaft, where the center axis of the stator cylinder is parallel with but spaced apart from the driveshaft axis. A magnet assembly is disposed in each end of the stator cylinder, with one magnet assembly engaging one cam and the other magnet assembly engaging the other cam. Each magnet assembly includes a cam follower that can move along a curvilinear shaped cam. A magnet slide arm attached to the cam reciprocates magnets carried on the magnet slide arm through electromagnetic windings disposed around the stator cylinder. An electrical input delivered to the windings can reciprocate the arm, driving the cams to rotate the driveshaft. Alternatively, rotation of the driveshaft can be used to reciprocate the arm to induce electric current in the windings.

CAM, FUEL INJECTION PUMP, AND ENGINE

The purpose of the present invention is to increase the pressure of fuel while reducing an increase in the maximum lift amount of a cam and deterioration of a fuel injection ability. This cam for use in a fuel injection pump that increases the pressure of fuel supplied into a fuel supply chamber by an axial movement of a plunger. The cam includes a first cam surface that causes an increase rate of an axial speed of the plunger when the cam rotates at a constant speed, in a pre-stroke period until the plunger increases the pressure of the fuel in the fuel supply chamber, to be a first increase rate, and a second cam surface that causes the increase rate of the axial speed of the plunger when the cam rotates at the constant speed, in a pressure increasing period that is a period from a start of increasing the pressure of the fuel in the fuel supply chamber by the plunger, to be a second increase rate, wherein the first increase rate is set higher than the second increase rate.

Wall-proximity furniture member having sync mechanism

A furniture member includes a base assembly, a frame assembly, a legrest mechanism, a support rod, and a sync mechanism. The frame assembly is movable relative to the base assembly among an upright position, a partially reclined position, and a fully reclined position. The legrest mechanism is movable relative to the frame assembly between a retracted position and a fully extended position. The support rod is supported by the frame assembly. The sync mechanism is coupled to and supported by the support rod. The sync mechanism is configured to prevent the frame assembly from moving from the upright position to the partially reclined position until the legrest mechanism reaches the fully extended position.

ASYMMETRIC CAM TRANSMISSION
20170342898 · 2017-11-30 ·

A torque drive transmission, having at least two counter-rotating cams bearing-mounted within a housing about a rotational axis. The counter-rotating cams are operative to: (i) convert a linear input to a rotary output, and (ii) drive a pair of coaxial drive shafts in opposite directions along the rotational axis. Furthermore, each counter-rotating cam defines a cam profile surface having drive and follower surfaces defining angles α and β respectively. The angles α and β are unequal to drive each cam and respective output drive shaft in an opposite rotational direction. As such, the cams may be driven in opposite directions irrespective the initial rotational position of the linear input, i.e., relative to each counter-rotating cam.
