The compressed fluid pump unit (1) for vehicles, which is capable of highly efficient and precise transfer, shall consist of a reservoir (2) for brake fluid, a master cylinder (3) in such pump connected to the reservoir, and a transfer circuit (15) at one end connected to the master cylinder and fitted to transfer nipples (19, 119, 219, 319, 419) connected to the reservoir (2). Efficient and precise, it will consist of a reservoir (2) for brake fluid, a master cylinder (3) in which the master cylinder is connected to the reservoir, and a transfer circuit (15) at one end connected to the master cylinder and fitted to transfer nipples (19,119,219,319, 419) which are normally closed to close the circuit and are constructed in such a way that the transfer circuit (15) is connected at the other end, which is the part that leads the end of the transfer nipples (19,119,219,319,419) to the reservoir (2).

Claims (22)

1. The pump unit in a hydraulic fluid compression system for vehicles, where the pumps use hydraulic fluid, consists of: a hydraulic fluid reservoir, a master cylinder in the hydraulic fluid compression system where the master cylinder is connected to the reservoir, and a transfer circuit where one end of the transfer circuit is connected to the master cylinder and the other end to the reservoir.

Pumping units in a pressurized fluid system as per Reservoir 1 where the reservoir includes an opening enclosed by a removable cover, and the transfer circuit continues with an outlet into the reservoir where the outlet does not point directly towards the opening. 10. The pump unit in the compressed fluid system according to claim 9, where the transfer nipple consists of a shank, the shank defines the axial cavity, and the outlet of the transfer circuit is directed radially through the transfer nipple from the axial cavity. 11. Pumping unit in a pressurized fluid system under claim 10 where the transfer nipple is further comprised of a head where the head includes an indication for inserting a key, which may be used to open and close the transfer nipple. 12. Pump units in fluid-pressurized systems as per claim 11, where the indication for the key is a recessed hexagonal shape. 13. Pump unit in a hydraulic fluid compression system for vehicles, where the pumps in the hydraulic fluid compression system use hydraulic fluid and consist of a hydraulic fluid reservoir, a master cylinder in the hydraulic fluid compression system where the master cylinder is connected to the reservoir, and a transfer circuit where one end of the transfer circuit is connected to the master cylinder and the other end to the reservoir, and where the transfer circuit includes a transfer nipple where the transfer nipple is fitted into the transfer circuit and where the transfer nipple is closed during the normal operation of the hydraulic fluid compression system pump unit in order to close the transfer circuit, and where the transfer nipple can be accessed through a hole formed in one of the walls of the reservoir, where the hole is parallel to one of the walls of the reservoir. 14. A pump unit in a fluid-pressurized system according to claim 13, where the reservoir consists of an opening and a cover, where the opening is sealed by a removable cover secured by several screws, and where the hole is sealed by one of several screws. 15. A pump unit in a compressed fluid system under claim 14 where the transfer nipple consists of a rod section, the rod section defines the axial cavity, and the outlet of the transfer circuit is directed radially through the transfer nipple from the axial cavity. 16. Pumping units in compressed fluid systems under claim 15 where the transfer nipple is further comprised of a head where the head includes an indication for inserting a key, which may be used to open and close the transfer nipple. 17. Pump units in fluid-pressurized systems according to claim 16, where the indication for the key is a recessed hexagonal shape. 18.
