[0003]

At this time, as shown in FIG. 3, a conventional oil lubricating apparatus for an internal combustion engine is usually an engine E.
The engine oil is supplied from the lubrication port Ia located on the side of the main body or on the upper surface (not shown) of the cylinder head. Since the opening Ia is close to the engine E body, the oil filter F, the engine support, the supplementary parts such as the battery, the space around the lubrication opening is narrow, and furthermore, the opening Ia is relatively deep in the bonnet. In some cases, lubrication work is difficult, and in some cases, visual monitoring of over-lubrication is inadequate, and oil overflows and contaminates the floor inside the hood.

[0004] In order to solve such a drawback, the present invention is directed to an engine according to the present invention, even if it is an existing bonnet-type engine-driven working machine, without drastically changing the installation position of the engine or the engine body. In addition to enabling the oil lubricating device of the driven work machine to be arranged, the lubrication of the specified amount can be performed smoothly because the lubricating amount is accurate and easy to visually monitor when lubricating the engine. It is an object of the present invention to provide an oil lubricating device for an engine driven working machine which does not contaminate the floor surface with engine oil overflowing from an oil inlet.

[0005]

As a means for solving the above problems, an oil lubricating device for an engine driven working machine according to the present invention is an oil lubricating device for an engine of an engine driven working machine housed in a bonnet. An oiling portion fixed in the bonnet and having a mark on the inner wall thereof for measuring the remaining amount of oil, an oiling portion for lubricating oil to the engine, a lower portion of the oiling hole, and an oil pan of the engine. And a connecting portion made of a material having heat resistance and vibration absorption.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An oil lubricating device for an engine-driven working machine according to the present invention will be described below with reference to the accompanying drawings.

First, FIG. 1 is a front view showing an embodiment of an oil lubricating apparatus 1 for an internal combustion engine according to the present invention, and FIG. 2 is an enlarged view of a part A of FIG. Symbol E used in these figures indicates an engine, symbol P indicates an oil pan of the engine E, symbol R indicates an oil inlet fixed to the oil pan P, symbol I indicates an oil inlet, Reference numeral C denotes a connecting portion connecting the oil inlet I and the inlet R, and reference numeral 2 denotes a bonnet in which the oil lubricating device 1 of the internal combustion engine is disposed.

A specific arrangement of the oil lubricating apparatus 1 for an internal combustion engine in the bonnet 2 having such a configuration will be described. The lubrication port I of the lubricating portion is a base 3 for mounting the engine E of the engine E inside the bonnet 2. In addition, the bonnet 2 is fixedly disposed in a protruding state at an appropriate free position where an operator on the base near the door 4 which is an opening of the hood 2 can be visually observed and lubricating work is easy. Of course, if there is another bonnet member convenient for fixing other than the base near the door 4, it may be used. In addition, a mark such as coloring for preventing over-lubrication is attached to a position visible to the operator inside the lubrication port I.

The height position of the lubrication port I fixedly disposed on the base 3 is determined by the mark on the inside thereof and the specified amount of oil of the engine E, that is, the specified amount of oil stored in the oil pan P. It is located at the same height as the indicated oil level position, and by arranging and fixing at such a position, it is easy to check the amount of oil stored in the engine and the like.

The lower tubular member of the injection port I fixed to the base 3 is bent in the direction of an oil inlet R protruding from the side of the oil pan P. The outer peripheral edge is pressed in a convex shape to prevent the detachment of the connecting member described later, similarly to the shape of the outer peripheral edge at the end of the oil inlet R.

An end of the lower oil-filled tubular member I to be bent and an oil inlet R protruding from the oil pan P are connected by a connecting portion C. The connecting portion C is made of a material having a vibration-absorbing property for preventing vibrations generated during operation of the engine E from being directly transmitted to the lubrication port I, and can withstand engine oil whose temperature has increased due to the operation of the engine E. The flexible pipe is made of a material having heat resistance, such as hard rubber. The material and shape of the connecting portion C are not particularly limited, and needless to say, the same operation and effect can be obtained as long as the material and shape satisfy the above conditions.

A procedure for checking the engine oil of the engine E provided with the oil lubricating device 1 for an internal combustion engine will be described below. First, when the engine E disposed inside the hood 2 is in operation, the operation is stopped, and the circulation of oil in the engine is stopped. Next, the door 4 located on the side of the bonnet 2 is opened, and the lid 5 engaging with the lubrication port I is detached. The lid 5 is detached, and oil is supplied to the inside of the oil supply port until the liquid level reaches the mark for preventing over-lubrication. As a result, a predetermined amount of oil to be stored in the oil pan P is injected.

According to such a procedure, when it is determined that the engine oil needs to be replenished or that the engine oil needs to be changed, the lubrication port I is provided after the predetermined operation is completed.
More lubrication is performed.

[0014]

As described above, the oil lubricating device for an engine driven working machine according to the present invention has the following effects.

(1) Even with the existing hood-type engine-driven working machine, the engine-driven working machine according to the present invention can be used without making significant design changes to the engine body, such as changing the installation position of the engine and the accessories. The oil lubrication device can be installed at any position. (2) Since the amount of lubrication to the engine can be easily visually determined, the specified amount of lubrication to the engine can be accurately performed. (3) Further, since the lubrication port can be installed at a free position, it can be installed near the door of the bonnet, and the lubrication work can be reliably performed. (4) Therefore, the floor surface in the bonnet is not contaminated with engine oil overflowing from the oil supply port to prevent over-lubrication and the like. This is an effect.
