COMPRESSOR SYSTEM, AND PUNCTURE REPAIR KIT USING SAME

摘要

The pressure of compressed air supplied to an object to be filled with air is controlled at a specified pressure or less without using a relief valve. Given that a cylinder volume (stroke volume) during a piston moves from the lower dead point to the top dead point is V1, a cylinder volume (compression volume) when the piston reaches the top dead point is V2, the atmospheric pressure is P0, and the specified pressure is PP, the compression volume V2 in the compressor system satisfies the following expression (1). The diameter D of the air intake hole of an air intake valve provided on the piston is 3 to 15 mm.;0.8×{V1×P0/(PP−P0)}=

1. A compressor system, in which a supply pressure of compressed air is controlled at a specified pressure PP or less without using a relief valve, and which is characterized by having
a motor, a piston driven by the motor through a crank mechanism, a cylinder havinga cylinder main body forming a pump chamber housing the piston reciprocably from a lower dead point to a top dead point and compressing air between the piston and itself, anda cylinder subpart forming a surge chamber for receiving the compressed air compressed in the pump chamber through an air release valve,
an air intake valve havingan air intake hole penetrating through the piston to take outside air into the pump chamber, and a valving element formed from a leaf spring closing a pump chamber side of the air intake hole with its elasticity, and
an air supplying passage for sending and supplying the compressed air from the surge chamber toward outside,wherein
the compression volume V2 satisfies the following expression (1), and the diameter D of the air intake hole is 3 to 15 mm,
0.8×{V1×P0/(PP−P0)}=
