Abstract:
A four-stroke engine comprises an oil tank (2), a crankshaft chamber (1), a distribution chamber (5), a rocker chamber (4), a combustion chamber (9), and a lubricating system. The oil tank (2) is communicated with the crankshaft chamber (1) through an oil supply channel (21). The crankshaft chamber (1) is communicated with the distribution chamber (5) through a first oil transmission channel (15) and a unidirectional valve (151) is disposed in the first oil transmission channel (15). The rocker chamber (4) is communicated with the crankshaft chamber (1) through at least one oil return channel (41), and a unidirectional valve (413) is disposed in each oil return channel (41). The distribution chamber (5) is communicated with the oil tank (2) and used for separating an oil-gas mixture into oil mist and fluid oil. The four-stroke engine further comprises a cam (7) and a transmission mechanism (8) connected between the cam (7) and a crankshaft of the crankshaft chamber (1) in a matched manner. The cam (7) is matched with a rocker (44) of the rocker chamber (4) and located above the combustion chamber (9). The four-stroke engine has a simple lubricating system, and is desirable in operation stability and low in noise.

The gas exchange opening (62) is disposed on the rotary axis (28), and a closing member (68) is disposed in the gas exchange opening (62) and is rotationally fixed to the piston cage (30) relative to the rotary axis (28), and is axially displaceable relative to the piston cage (30) in the direction of the rotary axis (28) for opening and closing the gas exchange opening (62), a control mechanism (74) for the closing member (68) being present and deriving the axial motion of the closing member (68) from the rotary motion of the closing member (68) about the rotary axis (28).
Abstract:
Sinn und zweck dieser Konstruktion (Ping-Pong Motor) ist es einen besseren Motor als der ausgereiffte Otto-Motor generell in vielen punkten zu konstruiren was uns auch gelungen ist. Billigere Herstellung,leichtere Bauweise, weniger bewegliche Teile, besserer Wirkungsgrad.
Abstract:
The invention relates to a cam actuator (2) for actuating at least one valve (3) slidably mounted in a mounting (1), the device comprising a tappet (8) which is to be mounted on a free end of a stem (3a) of the valve and which is mobile relative to the mounting (1); and a resilient return means (9) for the tappet, which to urge the tappet (8) against the cam (2), characterised in that the device comprises an electromagnetic locking means including an electromagnetic actuator (22) having a coil (24), preferably outside the tappet (8), and at least one pin (12) subjected to the magnetic field of the actuator (22), such that supplying power to the coil (24) causes the selective movement of the pin (12) between a locked position, in which the tappet (8) is translatably linked to the valve (3), and an unlocked position, in which the tappet (8) freely slides on the stem (3a) of the valve.

This invention relates to an engine (5) having axially opposed cylinders (C). The engine (5) has a first cylinder (C) having a first cylinder opening and a first cylinder head (H), a first piston (10) that reciprocates in the first cylinder opening, a second cylinder (C) having a second cylinder opening and a second cylinder head (H), and a second piston (30) that reciprocates in the second cylinder opening. The first cylinder opening and the second cylinder opening are in facing relationship such that the first cylinder and the second cylinder are axially opposed. The first piston (10) and the second piston (30) are connected such that the first piston (10) moves toward the first cylinder head (H) when the second piston (30) moves away from the second cylinder head (H) and such that the first piston (10) moves away from the first cylinder head (H) when the second piston (30) moves toward from the second cylinder head (H).
