Abstract (en)

The present invention realizes a simple method for preventing a pressure in a crank chamber from excessively increasing without leading to an increase in a weight and an escalation of cost and causing damage of a structure forming a pressurizing booster compressor. A compression chamber p is formed by a cylinder 12, a cylinder head 14, and a piston 16 reciprocable inside the cylinder 12. A rotation of an output shaft 28a of an electric motor 28 causes the piston 16 to reciprocate via a crank shaft 24. A sealed crank chamber c is defined inside a crank case 18. Further, a pressurized gas supply tube 38, which supplies pressurized gas to be compressed into each of the compression chamber p and the crank chamber c, is provided. The crank case 18 is formed from a hollow cylindrical body 20 and an end plate 22 facing the outside. A low-strength wall 50A (a partition wall having a lower strength than another partition wall), which is configure to be broken under an allowable maximum pressure of the crank chamber c, is formed on the end plate 22.
