Dispenser according to claim 1, wherein at least one passage (26) forms a passageway between the porous material part (3) and the reservoir (1) without passing through the plunger tube (4), such that the gas and the fluid product are simultaneously pushed through the porous material part (3) every time that the actuation wall (11) is pressed.4. Dispenser according to claim 3, wherein the passage (26) extends partially along the plunger tube (4).5. Dispenser according to claim 1, wherein the dispensing orifice (22) is formed by an end piece (2) installed on the opening (15) of the reservoir (1), the said end piece (2) forming a reception housing (24) in which the porous material part (3) fits.6. Dispenser according to claim 5, wherein the end piece (2) forms an attachment sleeve (25) with which the plunger tube (4) comes into contact with its connection end (42).7. Dispenser according to claim 6, wherein the attachment sleeve (25) is gripped in the reservoir opening (15).8. Dispenser according to claim 6, wherein at least one passage (26) is formed inside the sleeve (25) and extends as far as the reception housing (24).9. A fluid product dispenser comprising:a reservoir containing the fluid product and a gas, the said reservoir comprising an opening, a bottom, and an actuation wall that can be moved to reduce the volume of the reservoir, a dispensing orifice through which the fluid product is sprayed as a jet from the dispenser every time that the actuation wall is actuated, and a plunger tube that extends with a free end into the reservoir almost to its bottom, the said plunger tube comprising an opposite connection end through which fluid product is supplied to the dispensing orifice, a porous material part that can absorb fluid product by capillarity being placed between the plunger tube and the dispensing orifice, wherein the porous material part has a discharge end located in the immediate vicinity of the dispensing orifice so that the fluid product is sprayed as a jet from the dispenser upon actuation of the actuation wall; wherein the dispensing orifice is formed by an end piece installed on the opening of the reservoir, the end piece forming a reception housing in which the porous material part fits; and wherein the end piece comprises a body defining a dispensing end forming the dispensing orifice and an opposite attachment end provided with an attachment sleeve to which the plunger tube is connected, the inside of the said body forming the reception housing for the porous material part, the said housing and the said sleeve being aligned with each other such that the connection end of the plunger tube can come into contact with the porous material part. 10. A fluid product dispenser comprising:a reservoir containing the fluid product and a gas, the reservoir comprising an opening, a bottom, and an actuation wall that, when actuated, reduces the volume of the reservoir; a dispensing orifice through which the fluid product is sprayed as a jet when the actuation wall is actuated; a tube that extends with a free end into the reservoir, the tube comprising an opposite connection end through which fluid product is supplied to the dispensing orifice; and a porous material part that absorbs fluid product by capillarity, the porous material part disposed between the plunger tube and the dispensing orifice, and having a discharge end located in the immediate vicinity of the dispensing orifice so that actuation of the actuation wall forces a mixture of the fluid product and a gas to be discharged from the dispenser as the sprayed jet; and wherein the discharge end is in contact with the dispensing orifice. 11.
