摘要： An ejector has a variable nozzle structure and is installed in a fuel cell recirculation line to supply new hydrogen and a recirculation gas. The ejector includes: a first housing having a first hole through which hydrogen is supplied and an orifice through which the hydrogen is discharged; a second housing disposed in the first housing and having a second hole into which the hydrogen passing through the first hole flows; and a poppet penetrating a third hole defined at one side of the second housing. The poppet is configured to adjust an area of a space opened by the orifice discharging the hydrogen. The hydrogen flowing into the second housing is discharged through a space between the other side opposite to the one side of the second housing and the poppet to move to the orifice.

摘要： A solenoid valve includes: a valve housing having, at one end thereof, an inlet port through which a fluid is introduced and having, at the other end thereof, an outlet port through which the fluid is discharged; a solenoid provided in the valve housing and disposed between the inlet port and the outlet port; a first plunger provided at one end of the solenoid adjacent to the inlet port and configured to selectively open or close the inlet port by being rectilinearly moved by the solenoid; a first spring member configured to provide elastic force to allow the first plunger to move in a direction in which the first plunger closes the inlet port; a second plunger provided at the other end of the solenoid adjacent to the outlet port and configured to selectively open or close the outlet port by being rectilinearly moved by the solenoid in a direction opposite to the movement direction of the first plunger; and a second spring member configured to provide elastic force to allow the second plunger to move in a direction in which the second plunger closes the outlet port. The solenoid valve has a simplified structure while ensuring sealability.

摘要： A solenoid valve includes a valve housing having a first space that communicates with an inlet flow path and a second space that communicates with an outlet flow path. A solenoid is provided in the valve housing to surround the first space. A flow path guide is provided in the first space and has an inflow path communicating with the first space. A plunger is rectilinearly moved in the flow path guide by the solenoid. A valve member is connected to the plunger and opens or closes the outlet flow path based on a plunger movement. A spring member provides elastic force allowing the valve member to move in a direction in which the valve member blocks the outlet flow path. A fluid guide part is formed in the plunger and guides a fluid, supplied into the inflow path via the first space, selectively to the second space.
