A flow passage is provided in which working fluid such as oil that generates a break hydraulic pressure flows from the side of a solenoid valve through a filter, flows to the front of a plunger through a side hole formed in a valve body of the solenoid valve, and then flows along the side of valve body, that is, is discharged out of an outlet through a side space between valve body and a valve seat. Therefore, linear pressure control is easy because working fluid flows into toward the front of valve plunger through a side inlet of solenoid valve and the entire size is reduced because a special channel for guiding working fluid to the front of the valve plunger is not needed in a pump housing case. | 11-06-2008 |
| 20080252054 | AIR BAG CUSHION - An air bag cushion includes a lower chamber including at least one bottom panel and defining a lower space by an introduced gas, and an upper chamber including a plurality of top panels and a volume control panel and combined with the lower chamber, the volume control panel being disposed in at least any one of spaces between the top panels and defining an upper space together with the top panels. | 10-16-2008 |
| 20080216473 | MASTER CYLINDER OF BRAKE - A master cylinder of a brake is disclosed. The master cylinder includes a cylinder body connected with an oil tank and defining therein a first pressure chamber and a second pressure chamber, which are separated from each other by a partition, a first piston to perform reciprocating movements in the first pressure chamber, a second piston to perform reciprocating movements in the second pressure chamber, a first return spring to elastically support the first piston in the first pressure chamber, and a second return spring to elastically support the second piston in the second pressure chamber. The first piston has a plurality of recesses formed at one end thereof to assure smooth supply of oil during braking. The master cylinder has the effects of assuring smooth supply of brake oil during braking, and preventing fluctuation of a piston therein. | 09-11-2008 |
