Abstract: A 4-cycle engine including a crankshaft connected to a piston and supported at opposite ends by a crankcase for rotation. The crankshaft is formed at one of its two output shaft sections with a groove extending peripherally along the outer peripheral surface of one output shaft section substantially in the form of a endless loop having a cross point. A plurality of followers engaged in the groove have their movements transmitted, through respective linkages, to an exhaust valve and a suction valve respectively. A governor device is located at the other output shaft section and operative to actuate an engine rpm. controller depending on the speed of rotation of the crankshaft.

Abstract: An engine generator has an opening and closing mechanism including: a control shaft provided to a valve shaft of a choke valve to be rotatable relative thereto within a predetermined angular range; an urging member urging the valve shaft relative to the control shaft in a direction in which an opening degree of the choke valve decreases; a restriction mechanism that sets a minimum opening degree of the choke valve by restricting a range of rotation of the control shaft; a choke operating portion which, upon operation, drives the restriction mechanism in a direction in which the minimum opening degree of the choke valve decreases; and a negative pressure mechanism driven by a negative pressure generated during an operation of the engine to cause the control shaft to rotate to increase the minimum opening degree of the choke valve within the range of rotation restricted by the restriction mechanism.

Abstract: The invention relates to a valve mechanism for controlling a disc valve (1) of an internal combustion engine and comprises a control shaft (2) which is driven by the engine crankshaft, and a push rod (3) which is driven by the control shaft (2) and which for the purpose of transmitting reciprocating movement is connected to one arm (14) of a two-arm rocker (4) which is pivotable about a rocker shaft (15) and the other arm (16) of which rocker transmits these movements to the valve (1). The valve mechanism according to the invention is characterized in that the control shaft (2) is intended to act upon the push rod (3) in both directions of movement thereof; in that the first arm (14) of the rocker (4) extends essentially at right angles to the push rod (3) and the second arm (16) of the rocker extends essentially parallel with the longitudinal geometric axis of the valve (1); and in that a lifting arm (5) is provided for transferring rocker movement to the valve (1). The other arm (16) of the rocker (4) is provided with activating means (18) for coaction with the lifting arm (5), one end of which is pivotally mounted on a lifting arm shaft (19) and the other end of which is provided with means for activating the valve (1). The lifting arm surface (20) which co-acts with the second arm (16) of the rocker (4) is profiled in a manner to achieve the desired pattern of movement of the second end of the lifting arm (5) in response to movement of the rocker (4).
