Embodiment Construction

[0021] figure 1 A diversion unit 1 is schematically shown, comprising a supply port arrangement with a pressure port P and a tank port T. As shown in FIG. Pressure port P is connected to main flow path 2 . The reservoir port T is connected to the reservoir flow path 3 .

[0022] The pressure port P is connected to a pressure source 4 which in the present case comprises a pump 5 and a priority valve 6 . However, basically any other pressure source can be used.

[0023] The diversion unit 1 also includes a working port arrangement having a left working port L and a right working port R. As shown in FIG. The steering motor 7 is connected to the work ports L, R.

[0024] In the present case, the secondary flow unit 8 is connected to the working port means L,R. The secondary flow unit 8 may eg use electrohydraulic valves or other hydrostatic steering components. The secondary steering unit 8 can be used, for example, to remotely steer the vehicle.

[0025] The left working p...

Abstract

A hydraulic steering unit (1) is described comprising a supply port arrangement having a pressure port (P) connected to the main flow path (2) and a reservoir port (P) connected to the reservoir flow path (3) T); working port device having a left working port (L) connected to the left working flow path (9) and a right working port (R) connected to the right working flow path (10); bridging of variable orifices A device (15) having a first left orifice (A2L) connected to the main flow path (2) and connected to the left connection point (16) at the left working flow path (9), connected to the main flow path (2) and The first right orifice (A2R) connected to the right connection point (17) at the right working flow path (10), connected to the left connection point (16) at the left working flow path (9) and connected to the reservoir flow The second left orifice (A3L) connected with the channel (3), and the second right orifice connected with the right connection point (17) at the right working flow channel (10) and connected with the reservoir channel (3) (A3R). Such a steering unit should allow comfortable steering. For this purpose, an anti-backflow device (20, 21) is arranged in at least one of the left working flow path (9) and the right working flow path (10).

Description
