Title:
MULTI-POWER SOURCE COMPOSITE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/004419
Kind Code:
A1
Abstract:
A multi-power source composite control device. At least four control portions (111, 112, 113, 114) and at least two load flow channels (115, 116) are provided in a main body (1), the control portions (111, 112, 113, 114) each are provided with a main flow channel (1111, 1121, 1131, 1141); at least four switching members (21, 22, 23, 24) of a switching assembly (2) are assembled in the main flow channels (1111, 1121, 1131, 1141), respectively, the peripheral sides of the main flow channels (1111, 1121, 1131, 1141) are in communication with a plurality of branch flow channels, the main flow channels of every two control portions are respectively in communication with passages for outputting and inputting fluid of another power devices (4, 5); two load flow channels (115, 116) are in communication with two ends of a load (6), at least some of the branch flow channels of each of the control portions (111, 112, 113, 114) are in communication with each other, and the switching members (21, 22, 23, 24) are provided with lower flow guide ports (218, 228, 238, 248) in indirect communication with the main flow channels (1111, 1121, 1131, 1141), respectively. When the switching members (21, 22, 23, 24) are operated by an external force, the lower flow guide ports (218, 228, 238, 248) can be selectively in communication with the branch flow channels, so as to form various different fluid transmission paths in which the different power devices (4, 5) individually or collectively drive the load (6), and control therefor.
