Desynchronized coupling of a hydraulic machine

摘要

A hydraulic circuit. The circuit includes a high pressure line and a low pressure line, the pressure in the high pressure line being greater than the pressure in the low pressure line, a hydraulic machine having two ports designed to be connected to the high pressure and low pressure lines, a first of the ports being a hydraulic fluid intake port and the second of the ports being a hydraulic fluid discharge port The circuit includes a sequential connector designed to connect the ports of the hydraulic machine to the high and low pressure lines.

1. A hydraulic circuit including:
a high pressure line (HP) and a low pressure line (BP), the pressure in said high pressure line (HP) being greater than the pressure in said low pressure line (BP), a hydraulic machine (2) having two ports (21, 22) designed to be connected to said high pressure (HP) and low pressure (BP) lines, a first (21) of said ports being a hydraulic fluid intake port and the second (22) of said ports being a hydraulic fluid discharge port, wherein said circuit also includes a control line (PP), the pressure whereof is lower than the pressure in the lower pressure line (BP), and sequential connection means (4, 5, 8, 9) comprising at least one distributor (4, 9) designed for, during a first movement, connecting the intake (21) of the hydraulic machine to the control line (PP), during a second movement, connecting the discharge (22) of said hydraulic machine to the control line (PP), and, during a third movement, connecting the discharge (22) of said hydraulic machine (2) to the low pressure line (BP) and the intake (21) of the hydraulic machine (2) to the high pressure line (HP).
