1. Trochoid pump for transferring high-viscosity liquid under high pressure

2. Disclosed is a trochoid pump for transferring a high-viscosity liquid under high pressure.

3. The new type of rotary compressor has two key parts, an outer rotor and an inner one which employs isometric curve of trochoid as its profile.

4. In addition, the trochoid pump allows size and weight reduction and thus can be directly mounted on various robot arms in industrial settings and is applicable to various uses by having a large variable range for a discharge amount.
