<p>The charging valve has a valve body, having an upper surface with a number of apertures in positions, corresponding to those of a direction control valve (3), which is used in conjunction with the valve body. The lower side of the valve body has apertures, positioned in layer layers, corresponding to those of a distributor used with it. The valve housing has three back pressure valves (14-16). The steel sphere side of the first and second valve, and the spring side of the third valve, are connected to an aperture in that side, which is in contact with the rod side of the cylinder. The spring side of the first valve is connected to the aperture, which in turn is in contact with the oil supply channel.</p> |
