A foil bearing includes an outer member (11), and a plurality of foils (13) that are mounted to an inner circumferential surface (11a) of the outer member (11) and directly face the inner circumferential surface (11a) of the outer member (11) in a radial direction without interposition of another member (such as back foils). The foils (13) each include: holding portions (13a, 13b) that are formed at both circumferential ends and held while in contact with the outer member (11); and a body portion (13c) that is formed circumferentially between the holding portions (13a, 13b) and has a bearing surface (A). At least an end portion on one side in a circumferential direction of the body portion (13c) is raised radially inward with respect to the inner circumferential surface (11a) of the outer member (11).

摘要:
A mixed air amount alarm device is provided which determines the amount of air present in a hydraulic circuit between a hydraulic pressure source and an instrument driven by hydraulic pressure, and produces an alarm if the air amount is excessive, a situation is prevented in which an alarm is produced or not produced according to change of the air amount (volume) resulting from temperature change, and it is possible to stop an alarm if potential danger disappears and a safe state is recovered due to spontaneous release of air out of the hydraulic circuit. If the air amount is determined excessive, this is stored in a nonvolatile memory, and even if air amount excessiveness determination is not made at the next activation of the hydraulic device, the content of the nonvolatile memory is checked and an alarm is produced if air amount excessiveness determination has not been made before. It is preferable to add a function of erasing the air amount excessiveness determination history when specific conditions are met, for example, if the fluid temperature of hydraulic fluid or its inferred value is equal to or higher than a predetermined value, and in this state, the air amount is determined to be at a permissible level.
摘要:
A hydraulic pressure control device is proposed in which using a proportional pressure control valve having a built-in spool valve, the hydraulic pressure for wheel brakes is adjusted to a value corresponding to the magnitude of an external force applied to the spool valve, non-electrical pressure adjustment can be done both in a normal state and in an emergency, and the structure is simplified. The brake pedal is coupled through a spring to the spool valve of the proportional pressure control valve having a solenoid for generating a spool-driving force, and the brake pedal force is applied to the spool valve as an external force so that not only in an emergency but in a normal state, pressure is adjusted by the brake pedal force.
