[Brief explanation of the drawing]

Figures 1 to 6 show an embodiment in which this invention is applied to a garbage collection vehicle that collects garbage containing sewage.
The figure is a sectional view taken along the line - in Fig. 1 (when the tailgate is lowered), Fig. 3 is a sectional view taken along the - line in Fig. 1 (when the tailgate is raised), and Fig. 4 is a cutaway front view of the cylinder device for the tailgate. FIG. 5 is a hydraulic system diagram, and FIG. 6 is an electrical system diagram. Furthermore, Figures 7 and 8 show the main parts of a conventional garbage collection vehicle. Figure 7 is a cutaway side view of the main parts of a garbage collection vehicle that does not have a dedicated tailgate cylinder device, and Figure 8 is FIG. 2 is a perspective view of a main part of a garbage collection vehicle equipped with a dedicated tailgate cylinder device.

Amendment June 9, 1981 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] 1. A garbage collection vehicle equipped with a dedicated cylinder device for opening and closing the tailgate, wherein the cylinder device is disposed near the inner side of the side wall of the tailgate, and the cylinder device is of a double-acting type. A garbage collection vehicle characterized in that the constructed cylinder device is provided with a valve that opens an extension side oil passage within the apparatus by a predetermined oil pressure of a contraction side oil passage within the apparatus. 2. A utility model according to claim 1, characterized in that a deceleration mechanism is provided between the piston and the cylinder of the cylinder device to limit the amount of oil discharged from the cylinder at the end of the contraction stroke of the cylinder device. Garbage collection truck. 3. The cylinder device is arranged almost directly below the cylinder device for driving the ram panel, and one end is attached to the mounting bracket of the cylinder device for driving the ram panel, which is attached to the body of the garbage collection device, and the other end is attached between the pair of left and right side walls. The garbage collection vehicle according to Claim 1 of the Utility Model Registration Claim, characterized in that the garbage collection vehicle is attached to a deflector that extends over the vehicle. 4. The utility model registration according to claim 1, wherein the valve of the oil passage on the expansion side in the device is pushed open by a push pin driven by the predetermined oil pressure in the oil passage on the contraction side in the device. Garbage collection truck. 5. A utility model registration claim, in which the cylinder and the extension side oil passage are communicated through a guide hole, and a small diameter portion of the piston is guided by the guide hole to constitute the speed reduction mechanism. Garbage collection vehicles listed in Scope 2.

Claims (1)

[Claims for Utility Model Registration] 1. A garbage collection vehicle equipped with a dedicated cylinder device for opening and closing the tailgate, wherein the cylinder device is disposed near the inner side of the side wall of the tailgate, and the cylinder device is of a double-acting type.
