Abstract
A vehicle air compressor comprises a crankcase having a longitudinal central axis. The vehicle air compressor also comprises a head assembly including (i) a rear face that lies in a plane transverse to the longitudinal central axis of the crankcase, (ii) an air inlet port oriented in the same plane as the rear face, (iii) an air outlet port oriented in the same plane as the rear face, (iv) a coolant inlet port oriented in the same plane as the rear face, and (v) a coolant outlet port oriented in the same plane as the rear face.
Claims17
A vehicle air compressor comprising:
- a crankcase having a longitudinal central axis;
- and
- a head assembly including
- a rear face that lies in a plane transverse to the longitudinal central axis of the crankcase,
- a cylinder head, the cylinder head including an air inlet port oriented in the same plane as the rear face, an air outlet port oriented in the same plane as the rear face, and a coolant outlet port oriented in the same plane as the rear face, and
- a valve plate located between the cylinder head and the crankcase, the valve plate including a coolant inlet port oriented in the same plane as the rear face.
A vehicle air compressor comprising:
- a crankcase having a longitudinal central axis;
- a head assembly having
- a rear face that lies in a plane transverse to the longitudinal central axis of the crankcase,
- a cylinder head, the cylinder head including an air inlet port oriented in the same plane as the rear face, an air outlet port oriented in the same plane as the rear face, and a coolant outlet port oriented in the same plane as the rear face, and
- a valve plate located between the cylinder head and the crankcase, the valve plate including a coolant inlet port oriented in the same plane as the rear face;
- and
- at least one inlet reed valve positioned between the crankcase and the cylinder head and having a tongue axis that is transverse to the longitudinal central axis of the crankcase.
An air compressor comprising:
- a compressor head assembly defining a cylinder head having an air inlet port, an air outlet port, and a coolant outlet port, and a valve plate having a coolant inlet port, wherein the four ports are oriented in a common plane as a single face of the compressor head assembly;
- wherein the valve plate has a first serpentine-shaped internal coolant passage and the cylinder head has a second serpentine-shaped internal coolant passage that cooperates with the first serpentine-shaped internal coolant passage to provide enhanced cooling of the compressor head assembly during operation of the compressor.
A method of operating an air compressor having a rear face that lies in a plane, the method comprising:
- receiving intake air through an air intake port of a cylinder head, the air intake port oriented in the same plane as the rear face of the air compressor;
- delivering compressed air through an air discharge port of the cylinder head, the air discharge port oriented in the same plane as the rear face of the air compressor;
- receiving cooled coolant through a coolant inlet port of a valve plate, the coolant inlet port oriented in the same plane as the rear face of the air compressor;
- and
- delivering high-temperature coolant through a coolant outlet port of the cylinder head, the coolant outlet port oriented in the same plane as the rear face of the air compressor.
