Abstract

PURPOSE:To make shockless stop of a rocking device possible, by adding a function to stop the device through a cushioning travel in which the device decelerates by the work of a cushion throttle valve provided in the working oil circulation circuit, or a similar intermediate stopping function. CONSTITUTION:A rotary valve 2 is provided in the middle portion of a driving shaft 1 coupled to an output shaft of a rocking device, and a separator 14 for closing, near the ends of the rocking range, a connecting port 7 located at the ends of a plurarity of arc-shaped oil passage 3-6 provided on the outer periphery of a valve plate portion integrated to the driving shaft 1, on which the valve 2 is made up, is formed in a body to the driving shaft 1. The separator 14 is made to a sector-shape and is arranged so that two oil chambers 16, 17 are separately formed between the sector 14 and a stopper 15 also of a sector shape and is fixed to the main body side. The oil chambers 16, 17 are connected to each other through a cushion passage 36 consisting of oil passages 18, 19 and a throttle valve 20, which arrangement makes a cushioning action start at 18 degrees before the ends of the rocking operation range.
