Oil squirter

An internal combustion engine comprising:

• a cylinder defined by a cylinder bore;
• a piston configured to reciprocate within the cylinder bore;
• an oil pump configured to generate oil pressure;
• and an oil squirter having:
• a housing in fluid communication with the oil pump;
• a first nozzle in fluid communication with the housing and configured to spray oil onto the cylinder bore;
• a second nozzle in fluid communication with the housing and configured to spray oil at the underside of the piston;
• and a mechanism arranged within the housing and having an internal piston that defines a fluid passage and is configured to open the first nozzle and close the second nozzle when the oil pressure is below a threshold value and open the second nozzle and close the first nozzle when the oil pressure is at or above the threshold value;
• wherein:
• the internal piston remains in a first position when the oil pressure is below the threshold value and is shifted by the oil pressure to a second position when the oil pressure is at or above the threshold value;
• when the internal piston is in the first position, the fluid passage supplies oil to the first nozzle;
• and when the internal piston is in the second position, the fluid passage is blocked off and oil is directed around the internal piston to the second nozzle.

A vehicle comprising:

• an internal combustion engine configured to propel the vehicle, the engine including a cylinder defined by a cylinder bore, a piston configured to reciprocate within the cylinder bore, and oil pump configured to general oil pressure;
• and an oil squirter having:
• a housing in fluid communication with the oil pump;
• a first nozzle in fluid communication with the housing and configured to spray oil onto the cylinder bore;
• a second nozzle in fluid communication with the housing and configured to spray oil at the underside of the piston;
• and a mechanism arranged within the housing and having an internal piston that defines a fluid passage and is configured to open the first nozzle and close the second nozzle when the oil pressure is below a threshold value and open the second nozzle and close the first nozzle when the oil pressure is at or above the threshold value;
