Oil passage for supplying oil

An oil passage which supplies hydraulic oil to a cylinder deactivation apparatus (CDA) that operates by hydraulic pressure may include a high pressure passage, a low pressure passage, and an orifice, all of which may be integrally formed in either a cylinder head or a cam carrier. The high pressure...

Beschreibung
Zusammenfassung:	An oil passage which supplies hydraulic oil to a cylinder deactivation apparatus (CDA) that operates by hydraulic pressure may include a high pressure passage, a low pressure passage, and an orifice, all of which may be integrally formed in either a cylinder head or a cam carrier. The high pressure passage may be connected to an oil supply apparatus and receive oil therefrom. The low pressure passage may be coupled to the high pressure passage and receive pressurized oil therefrom and form a low pressure relatively lower than a pressure in the high pressure passage. The low pressure passage may be connected to supply a hydraulic pressure to the CDA. The orifice may couple the high pressure passage to the low pressure passage, communicate the high pressure passage and the low pressure passage and may be formed to supply oil from the high pressure passage to the low pressure passage.
