Title: ALL-IN-ONE Volume Booster
Inventor: KIM YOUNG WON
IPC: F15B11/04
Filed: 2021-07-26
Abstract: The present invention aims to provide an all-in-one volume booster in the form of a structural assembly, wherein all the functions of volume booster parts, such as a flow control device and a solenoid valve, are incorporated to allow for compaction by eliminating the need for piping work to connect the parts. The all-in-one volume booster in the form of a structural assembly according to the present invention comprises: a housing comprising an input port for receiving fluid, an output port for introducing the fluid into an actuator, a discharge port for discharging the fluid to the outside, a lower chamber for receiving the fluid introduced through the input port via a first flow path, and an upper chamber for receiving the fluid introduced through the input port via a second flow path; a filter part provided in the housing and removing impurities from the fluid introduced through the input port; an operating part provided in the housing and operated by a fluid pressure difference between the lower chamber and the upper chamber; a flow rate control part including a first control part for controlling a flow rate of the fluid introduced through the input port and a second control part for controlling a flow rate of the fluid discharged to the outside through the discharge port; a pilot regulator provided on one side of the housing and operating the operating unit by controlling a pressure of the fluid from which impurities have been removed by the filter part; and a connection block provided on a side of an upper end of the housing and transmitting the fluid whose pressure has been controlled by the pilot regulator into the housing.
