Unitary reciprocating motor and compressor with gas cushioning |
摘要 |
An electric motor driven compressor includes a reciprocating free-stroke armature driving a compressor piston in a cylinder. A cylinder head closes the cylinder to form a compression chamber into which opens an intake passage and an output passage selectively closed by valves. The output passage provides an opening into the compression chamber through the cylinder wall at a selected distance from the cylinder head to provide an energy absorbing chamber filled with gas when the piston closes the opening of the output passage during its compression stroke. The energy absorbing gas cushion in the chamber prevents impacts between the piston and cylinder head under varying operating conditions.
