Title: HYDRAULICALLY ACTUATED TRANSMISSION
Abstract:
A hydraulically actuated transmission (1) includes: a pressure-reducing valve (41) that is provided to a lubricant supply circuit (31), and reduces the pressure of a lubricant having a predetermined pressure and outputs the same; and a switching device (switching valve 51) that selectively switches a supply path between a first path (61) and a second path (62), said supply path extending from the pressure-reducing valve (41) to a part (71) to be lubricated by the lubricant. When the second path (62) is selected by the switching device, the pressure-reducing valve (41) increases the output pressure of the lubricant from the pressure-reducing valve (41) in comparison to when the first path (61) is selected.
