    Abstract: A four-cycle engine includes a cylinder block defining a cylinder bore. A piston is reciprocally disposed within the cylinder bore. A cylinder head member closes an end of the cylinder bore to define a combustion chamber together with the cylinder bore and the piston. The cylinder head member defines an inner passage having a first end communicating with the combustion chamber and a second end terminating at an outer surface of the cylinder head. A valve assembly having a valve section and an actuateable section is provided. The valve section is selectively placed at an open position and a closed position to connect and disconnect the inner passage with the combustion chamber, respectively. The actuateable section is formed oppositely from the valve section. A valve actuation mechanism is arranged to actuate the actuateable section to move the valve section between the open position and the closed position. The cylinder head member further defines a guide opening through which the actuateable section is slideably disposed. An external conduit defines an outer passage communicating with the inner passage. The external conduit depends from an end portion of the cylinder head member. The cylinder head member still further defines a recessed portion between the guide opening and the second end of the inner passage.

    Abstract: A valve collet concentrically mounted onto a circumferential groove of a valve of a desmodromic valve system for retaining a shim concentrically mounted on the valve of the desmodromic valve system, the shim having an inside surface of a given shape. The valve collet comprises an inner surface having an interlocking portion in the shape of the circumferential groove, the interlocking portion being interlocked with the circumferential groove. The valve collet further comprises an outer surface protruding away from the interlocking portion, the outer surface having a retaining portion matching the shape of the inside surface of the shim and cooperating with the same so as to have an increased contact area with the inside surface and thereby to improve retaining of the shim. Preferably, the inner surface of the valve collet comprises a securing portion extending longitudinally along the valve so as to secure mounting of the valve collet on the valve. Because of its increased contact area with the shim and because of its design, the valve collet does not quickly wear out and/or change in shape, remains properly seated in its bedded position, and thus extends the time interval allowable between regular valve adjustments.

    Abstract translation: 一个同心安装在去污型阀门系统的阀的圆周槽上的阀夹，用于保持同心地安装在去污型阀系统的阀上的垫片，该垫片具有给定形状的内表面。 所述阀筒夹具有具有周向槽形状的互锁部的内表面，所述互锁部与所述周向沟槽互锁。 所述阀夹还包括从所述互锁部分突出的外表面，所述外表面具有与所述垫片的内表面的形状相匹配的保持部分，并与所述锁定部分的内表面配合，以便与所述内表面具有增加的接触面积; 从而改善垫片的保持。 优选地，阀夹头的内表面包括沿着阀纵向延伸的固定部分，以确保阀夹头安装在阀上。 由于其与垫片的接触面积增加，并且由于其设计，阀夹头不会快速磨损和/或形状变化，保持适当地位于其位置，因此延长了常规阀门调节之间允许的时间间隔。

    Abstract: A tappet assembly for use with a valve train mechanism of an internal combustion engine that has angulated intake and exhaust valves actuated by the lobes of a pair of camshafts characterized in that the lobe of each camshaft serves to move the associated valve through an inverted bucket tappet incorporating a cylindrical force transmitting element which includes a surface that is skewed or inclined with respect to the bottom of the body of the tappet.

    Abstract: There is provided a structure of a shim to be inserted in a clearance provided between a cam and a tappet in a moving valve mechanism of an internal combustion engine, wherein a volumetric density of the shim body is changed such that it is maximized at an upper surface of the shim, at which the shim is in contact with the cam when a compression load or shock from the cam is applied to the shim, and the density is gradually decreased from the maximized portion to a lower or peripheral portions.

    Abstract: A gauge for measuring the clearance between a cam of an engine camshaft and the relevant valve, during rotation of the camshaft, comprises a first movable feeler element, for contacting the cam profile, and a second movable feeler element, for contacting a surface, facing the cam, of the valve or of an element coupled to the valve. A retraction device can displace the second feeler element from a rest position to an operating position. Gauging heads provide a signal depending on the mutual position of the first and second feeler elements and a processing circuit processes these signals to obtain the clearance.
