PUMP, IN PARTICULAR FOR CRYOGENIC MEDIA

摘要

The invention relates to a displacement machine, in particular a pump with a piston that is arranged inside a cylinder chamber. According to the invention, the cylinder wall is at least partially formed from an insulating material, said material having a high durability, a high modulus of elasticity, a low thermal conductivity and a low thermal capacitance and being capable of absorbing the compressive forces of the cylinder and tensile forces.
