Problems solved by technology

In addition to the additional cost associated with the provision of such a lost return spring, the presence of a shut-off HLA also requires a much larger space in the cylinder head, complicating the assembly of the entire valve train system

Embodiment Construction

[0016] Referring now to the drawings which are not intended to limit the invention, figure 1 Denotes a valve control system for controlling an engine mushroom valve generally denoted by 1 , the engine mushroom valve including a valve stem 13 . It should be fully understood by those skilled in the art that the present invention should not be limited to any particular type or configuration of engine mushroom valves, eg, solid rather than hollow, forged rather than deep drawn, and the like.

[0017] figure 1 Denotes a valve shutoff assembly (valve shutoff mechanism) generally indicated at 15, those skilled in the art will understand that the valve shutoff assembly 15 will typically be housed within a similarly shaped in the matching concave surface of . However, those skilled in the art will appreciate that the practice of the present invention need not employ the modular construction shown here. The valve stop assembly 15 includes an assembly housing 17 that preferably define...

Abstract

A valve control system (15) in which there is provided a deactivating rocker arm (51 ) disposed beneath a conventional, upper rocker arm (27), and disposed within a module housing (17). The deactivating rocker arm includes a latch tab (63) and when the latch tab engages (FIG 3) a latch member (65), the system operates in a normal, valve activating mode. When the latch member is in an unlatched condition (FIG 4), the deactivating rocker arm pivots, compressing the valve return spring (41), which thereafter serves as the required lost motion spring, biasing the deactivating rocker arm (51) and lash compensation device (35) back toward their normal position.

Description

technical field [0001] The present invention relates to a valve control system for controlling an engine fungus valve of an internal combustion engine, and more particularly, the present invention relates to a valve control system of the valve stop (valve stop) type. Background technique [0002] Although the valve control system of the present invention can be used to introduce some additional clearance in the mushroom valve train of the engine and thereby make the valve opening and closing degree smaller than the normal opening and closing degree, the present invention is extremely suitable for introducing a certain clearance in the valve train. A sufficiently large gap (hereinafter also referred to as backlash) so that the valve does not need to be opened and closed at all, and the present invention will be described in relation to this technology. Vehicle manufacturers wish to incorporate such valve closing capabilities into their engines, so that, for example, several o...
