Title:
A FLUID POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/066069
Kind Code:
A1
Abstract:
A fluid power device (100) includes a pressure auxiliary (140) and a flow restricting generator (120) connecting with the pressure auxiliary (140). The flow restricting generator (120) includes: a fluid storage tank having a fluid inlet and a fluid outlet; a flow restricting generating piston (123) sealingly sliding within the fluid storage tank; a force rod (135) connected between the pressure auxiliary (140) and the flow restricting generating piston (123). The force rod (135) transfers the acting force produced by the pressure auxiliary (140) to the flow restricting generating piston (123) so as to make it slide, thus discharging the fluid in the fluid storage tank from the fluid outlet and generating the fluid power.
