摘要： Reciprocating apparatuses such as a displacer in a Stirling engine or Vuilleumier (thermally-driven) heat pump and such as a poppet valve in an internal combustion engine have been known to be built with a mechatronic actuator. The reciprocating element has two springs in compression biased against each other. It has been found that conventional springs in compression introduce losses. A spring is disclosed in which a portion of the coil is wound in a clockwise direction and a portion is wound in a clockwise direction. Also, in reciprocation, the spring is in compression at one end of travel and in tension at the other end of travel.

摘要： In an engine electromagnetic valve operating device (20), an intake valve (17) is opened and closed by means of a first electromagnet (21), which is fixed to a cylinder head, and a second electromagnet (22), which is pivotably supported on the cylinder head by a fixed shaft (38) so as to be capable of swinging, attracting a first attraction face (23b) and a second attraction face (23c) respectively of an armature (23) having one end pivotably supported on the cylinder head by the fixed shaft (38) so that it can swing and having the other end abutting against a stem (18) of the intake valve (17). In this arrangement, by changing the angle between the first and second electromagnets (21, 22) by swinging the second electromagnet (22), the amount of lift of the intake valve (17) can be changed freely. Furthermore, since only at least one of the first and second electromagnets (21, 22) needs to be made to swing and, moreover, it is unnecessary to move the position of the armature (23), it is possible to form the electromagnetic valve operating device (20) compactly.

摘要： An internal combustion engine is provided with a plurality of valves, including a main driving valve and a driven valve, each of which can be lifted in response to an instruction from a control apparatus, and a lift sensor which detects a lift amount of the main driving valve. The control apparatus controls the lift of the driven and main driving valves based on an output of the lift sensor. The engine may also include a proximity sensor which detects whether the position of the driven valve is within a predetermined range, and a crank angle sensor. The control apparatus monitors the output of the proximity sensor to determine whether the driven valve is out of synchronization with respect to the crank angle, and performs an initial driving control that initializes the positions of the driven and main driving valves corresponding to the driven valve when loss of synchronization is detected.
