Description

2254113 1 TITLE: A CYLINDER HAVING A PISTON ASSEMBLY CAPBABLE OF STOPPING
ONCE WHEN HAVING MOVED UP AND DOWN EVERY TIME 1 This invention relates to a cylinder having a piston assembly capbable of stopping once when having moved up and down every time.
It is found that the volume efficiency of the prior art cylinder cannot be enhanced on account of insufficient intake air. Although it is proposed to open the valve 'earlier and delay the close thereof or use a turbo-charger to obviate the drawback, the function will still be limited and the cylinder cannot provide higher volume efficiency as the piston quickly moves and the time for intaking air is shortened. 15 It is, therefore, an object of the present invention to provide a cylinder which may obviate and mitigate the above-mentioned drawbacks. This invention relates to a cylinder having a piston which will stop once when moving up and down every time. 20 It is the primary object of the present invention to 2 provide a cylinder which may increase the volume efficiency.
It is another object of the present invention to provide a cylinder which has sufficient intake air and cooling time even when the piston quickly moves up and down.
Other objects and merit and a fuller understandings of the present invention will be obtained by those having ordinary skill in the art when the following detailed description of the preferred embodiment is read in conjunction with the accompanying drawings.
FIG. 1 is a sectional view of a cylinder according to the present invention; FIG. 2A is a sectional view of the guide plate of the cylinder according to the present invention; FIG. 2B is a fragmentary view of a guide plate of the cylinder according to the present invention; FIG. 3 shows how the present invention works; FIG. 4 is a sectional view showing the function of the present invention.
3 With reference to the drawings and in particular to FIGS. 1 and 2 thereof, the present invention mainly comprises a pinion 1, a gear 2 with two times the diameter of the pinion 1, a linking rod 3, a main crankshaft 4, an auxiliary crankshaft 5, a dovetail guide plate 6, and a piston assembly 7. The pinion 1 and the gear 2 are respectively mounted on the auxiliary crankshaft 5 and the main crankshaft 4 and are separated by a fixed distance via the linking rod 3 so that the pinion 1 and the gear 2 are meshed together in rotation. The upper and lower ends of the linking rod 3 are respectively connected to the auxiliary crankshaft 5 and the main crankshaft 4 which is the driving axle. The auxiliary axle 5 is driven by the gear 2 and provided with two dovetail ends which is capable of moving vertically along the dovetail guide plate 6. The dovetail guide plate 6 ( see FIG. 2) is constituted by a base 61 and an adjusting block 62 on which there is an elliptical threaded hole 621 utilizing a screw 622 to regulate the distance between the adjusting block 62 and the base 61. The piston assembly 7 is driven 4 by the auxiliary crankshaft 5.
The present invention is driven by the main crankshaft 4 which drives the pinion 1 fixed on the main crankshaft 4 to rotate the gear 2 with respect to the point P. The gear 2 is fixedly connected with the auxiliary crankshaft 5 which is provided with two dovetail ends slidably fitted with the dovetail guide plate 7. Hence, the auxiliary crankshaft 5 may drive the piston assembly 7 to move up and down. Referring to FIG. 3, there is shown the connection between the gear 2, the pinion 1 and the piston assembly 7. As the piston assembly 7 is located at the uppermost position, the pinion 1 is set to be located at zero degree ( see FIG. 1). Since the diameter of the gear 2 is two times the diameter of the pinion 1, the gear 2 will rotate 90 degrees in counter clockwise direction when the pinion 1. rotates 180 degrees with respect to the point P in clockwise direction ( see FIG. 3). Hence, if the pinion 1 has a diameter of 1 inch and the gear 2 has a diameter of two inches, then both of them will move one inch downwards and the piston assembly 7 will move two inches downwards. Meanwhile, the linking rod 71 rotates from point E and point A. As the pinion 1 further rotates to 360 degrees with respect to the point P in clockwise direction to raise 1 inch, the gear 2 will rotate to 180 degrees in counterwise direction to drive the piston assembly 7 via the auxiliary crankshaft 4 to move 1 inch downwards ( see FIGS. 3 and 4). As a result, the linking rod 71 will move from point A to point B thereby moving the piston assembly 7 up and down and then returning it at the original position ( see NO. 3 in FIG.
3 When the pinion 1 further rotates to 540 degrees in clockwise direction, the pinion 1 will move 1 inch downwards while the gear 2 will move to 270 degrees in counterwise direction thereby moving the piston assembly 7 to move 1 inch upwards and the linking rod 71 from point B to point C. Hence, the piston assembly 7 will move up and down and then returns to its original position. When the pinion 2 rotates to 0 degree in'clockwise direction ( see NO. 1 in FIG. 3), the pinion will move 1 inch upwards and 1 6 the gear 2 will rotate to 360 degrees and move 1 inch upwards too thereby moving the linking rod 71 from point C to point D and therefore, causing the pison assembly 7 to move 2 inches upwards. Thus, the piston assembly 7 will stop for a time after having moved up and down once.
Looking now at FIG. 4, there is shown an application of the present invention to an air compressor. In the application, when the piston assembly 7 will return to its lowermost point after having compressed the air, the piston assembly 7 may move two upward and downward strokes at its original position. In the meantime, the cylinder may sufficiently intake air and cool, although the piston assembly 7 quickly moves up and down thereby i-ricreasi.rig the volume efficiency of the cylinder. Moreover, when the piston assembly 7 stays at the stop stroke, the gear 2 and the pinion 1 will still rotate without loading, so that the energy will be stored in the piston assembly 7 which will then be able to compress the air in a short time.
Although the present invention has been described in a certain degree of particularity, it is understood that 1 7 the present disclosure is made by way of example only and that numerous changes in the detail of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
