| 41. | CAPTION : Opening the drain valve under the expansion tank after shutting off inlet valve enables you to drain the tank.
|
| 42. | The advantage of the design should have been very early ( 0-5 degrees before top dead centre ) opening inlet valve.
|
| 43. | The float is lifted upward by inertia, closing the fuel inlet valve as if the fuel bowl was full of fuel.
|
| 44. | This causes the opening times of the inlet valves to be very short, putting great strain on a delicate mechanical part.
|
| 45. | The benefit of this is that large solenoid current is not required to open the inlet valve against high pressure steam.
|
| 46. | This down-stroke of the piston, which is called the induction stroke, is timed to coincide with the opening of the inlet valve.
|
| 47. | If the machine doesn't fill as fast as it used to, it may be a sign the water inlet valve needs replacing.
|
| 48. | Its inlet valve regulated the flow of ventilating air to the cabin; its discharge valve opened as directed to maintain the required pressure.
|
| 49. | After establishing the location for the power unit and inlet valves, outline the best route to connect them with trunk and branch lines.
|
| 50. | This slowly lowers the water level inside the tank until it drops enough to open the ballcock ( inlet valve ) and start refilling.
