摘要： A guiding device (1) for guiding an impact head (100) of a homogenizing valve (200), said guiding device (1) comprising:
- a solid body (2) having a cylindrical symmetry and having an internal cavity (3) passing through the solid body (2), the internal cavity (3) developing according to an axis of symmetry (A-A) of the solid body (2), the solid body (2) having a plurality of passages (4) that are obtained for allowing the passage of a fluid;
- a sleeve (9) fitted within the internal cavity (3) of the solid body (2) for receiving the impact head (100).

摘要： A membrane-based piston pump (1) for use in a homogenising apparatus (100), comprising:
- a membrane means (2) separating a product side for a fluid product (P1) from a hydraulic side for a hydraulic fluid (P2);
- a reciprocating piston (3) operatively active on the hydraulic fluid (P2);
- valve means (4) configured to establish a selective fluid communication between the hydraulic side and a tank (10) containing the hydraulic fluid (P2),
wherein said valve means (4) comprise:
- a first valve arrangement (5, 6) that, in a working condition of the piston pump (1), is configured to discharge the hydraulic fluid (P2) having a pressure over a first predefined threshold from the hydraulic side towards the tank (10) and to draw the hydraulic fluid (P2) from the tank (10) to the hydraulic side in response to a pressure in the hydraulic side dropping below a second predefined threshold;
- a second valve arrangement (7, 8) that, in at least one non-working condition of the piston pump (1), is configured to discharge the hydraulic fluid (P2) having a pressure over a third predefined threshold from the hydraulic side towards the tank (10).
