Abstract
A vibration-type oil separator includes a housing having a blow-by gas entering path through which a blow-by gas enters, an oil-discharging path which discharges an oil separated from the blow-by gas to outside, and a gas-discharging path which discharges a gas obtained by separating the oil from the blow-by gas to the outside. A vibration cylinder has an orifice formed thereon for escaping the gas and generating vibration by a back pressure of the blow-by gas and an external force applied to the housing to separate the oil and the blow-by gas. A fixing rod fixes the vibration cylinder in an internal space of the housing, in which both side portions thereof are fixed to the housing and a central portion thereof is fixed to the vibration cylinder.
Claims12
A vibration-type oil separator, comprising:
- a housing having a blow-by gas entering path which is formed on a side face thereof and through which a blow-by gas enters, an oil-discharging path which is formed below the blow-by gas entering path and discharges an oil separated from the blow-by gas to outside, and a gas-discharging path which is formed above the blow-by gas entering path and discharges a gas obtained by separating the oil from the blow-by gas to the outside;
- a vibration cylinder having a bell shape and provided on the blow-by gas entering path, the vibration cylinder having an orifice formed thereon for escaping the gas and generating vibration by a back pressure of the blow-by gas and an external force applied to the housing to separate the oil and the blow-by gas;
- and
- a fixing rod fixing the vibration cylinder in an internal space of the housing, both side portions thereof fixed to the housing and a central portion thereof fixed to the vibration cylinder.
A blow-by gas recirculation system, comprising:
- a vibration-type oil separator including a lower body which has an oil outlet port formed thereon and is perpendicular to a blow-by gas inlet port formed on a side face of the lower body, a vibration cylinder having a blow-by gas passing through an internal space of the lower body to separate the blow-by gas and an oil by vibration caused due to a back pressure of the blow-by gas and engine vibration, a fixing rod having both side portions fixed to the lower body and a central portion fixed to the vibration cylinder, a flow-guiding body connected to the lower body and having an internal space in which the gas escaped through an orifice of the vibration cylinder is collected, a gas-discharging body having a gas outlet port through which the gas that is discharged from a hollow tube passage communicating with the internal space of the flow-guiding body and then collected is discharged, a gas guide spaced apart from the gas outlet port and protruding upwards in the internal space of the gas-discharging body, a diaphragm separated from the gas guide by a pressure of the gas collected in the internal space of the gas-discharging body so that the gas guide communicates with the gas outlet port, and a cap isolating the internal space of the gas-discharging body from outside and elastically supported by an elastic member;
- a blow-by gas entering line connected to the blow-by gas inlet port and supplying the blow-by gas generated in a cylinder block to the lower body;
- a gas-discharging line connecting the gas outlet port and an intake manifold using the cylinder block and delivering the gas, which is obtained by removing the oil from the blow-by gas, to the intake manifold;
- and
- an oil-discharging line connecting the oil-discharging port and an oil pan using the cylinder block and delivering the oil separated from the blow-by gas to the oil pan.
