DEVICE AND METHOD FOR FLUID MASSES INJECTION Russian patent published in 2015 - IPC F04B7/04 F04B15/02 

FIELD: personal use articles.

SUBSTANCE: invention relates to a device for injection of a fluid mass such as a food product. The device has the main body (3) with a hollow space (7) that is connected to the mass source (6), via fluid medium, through the inlet hole (7a) and to the main body destination - through the outlet hole (7b). The inlet hole (7a) and the outlet hole (7b) are positioned on the main body (3) at a distance from each other in the direction (L). Additionally, the device has the first body (1; 1') and the second body (2; 2') that are capable of movement within the hollow space (7) of the main body relative to the main body (3) and relative each other along the direction (L). The first body (1; 1') and the second body (2; 2') are adjacent to the inner wall with a sealing so that to enable sliding across such inner wall and limit the chamber (8; 8'). Due to movement of the first body (1; 1') and/or the second body (2; 2') one can vary both the chamber volume (8; 8') and the chamber positioned relative to the main body (3).

EFFECT: design simplification, performance increase.
