Title:
STATIC PRESSURE FLUID SUPPORT DEVICE
Document Type and Number:
Japanese Patent JP2019210954
Kind Code:
A
Abstract:
To provide a static pressure fluid support device capable of quickly changing a pressure in a static pressure pocket according to magnitude of disturbance load in a case when the disturbance load generates in the static pressure fluid support portion, and adjusting a thickness of a fluid film formed between guide surfaces to a proper thickness in a short time.SOLUTION: A static pressure fluid support device 1 includes a static pressure pocket 20, a fluid supply device 30, a fluid supply flow channel 40, a supply-side fixed throttle 50, a fluid discharge flow channel 60, a discharge-side active type variable throttle valve 70 for adjusting a flow rate of the fluid discharged to a drain portion 21 by displacement of a valve element 86 through a connection member 79 by operations of a valve portion 78, the connection member 79 and an actuator 71, a clearance detection portion 90 detecting a clearance α between a guide surface 12a and a guide surface 11a, and a control device 100.SELECTED DRAWING: Figure 1
