摘要：
A progressive hydraulic distributor which comprises a control block (2) containing three pistons (5, 6, 7) disposed at the vertices of an ideal triangle and ducting (4) for the lubricant fluid, and is removably supported on a second block (3) comprising only ducts (32C, 44, 80, 44A, 43, 44C) with a purely distributing function.
The connections between the ducts of the second block and the ducting of the first block are made by way of several ports, and in particular by passage ports comprising two distinct holes which are in mutual communication but can be separated from each other by O-rings, these connections being such as to enable the output fluid flow rate to be varied without disconnecting any pipe connected to a user.
