Claims

[Scope of utility model registration request]

In a high pressure generator, a suction side low pressure check valve and a discharge side high pressure check valve are provided in a valve block opposite to a high pressure plunger integral with a piston provided in a cylinder connected to a boost pump. The low pressure passage and the high pressure passage on the discharge side are formed at an acute angle from the high pressure plunger side, and a low pressure check valve on the suction side and a high pressure check valve on the discharge side are removably disposed on the outside respectively. Characteristic high pressure generator.
