| 摘要 |
The invention relates to a pressure reducer (1), comprising an outer cylinder (2) with a first air supply connector (A1) on a first end side (C1) of the outer cylinder (2) and a second air supply connector (A2) on a second end side (C2) of the outer cylinder (2), and a piston (3) which can be guided movably in the outer cylinder (2) with a first end-side front surface (S1) and a second end-side front surface (S2), wherein a first air chamber (K1) is arranged between the first air supply connector (A1) of the outer cylinder (2) and the first front surface (S1) of the piston (3), and a second air chamber (K2) is arranged between the second air supply connector (A2) of the outer cylinder (2) and the second front surface (S2) of the piston (3), wherein the surface areas of the two front surfaces (S1, S2) of the piston (3) are of different size, and wherein the pressure reducer (1) is suitable for reducing a second air pressure (P2) which prevails in the second air chamber (K2) in a pulsed manner proportionally to a first air pressure (P1) which prevails in the first air chamber (K1), by a first air connection (4) which consists of two parts (4a, 4b) being configured between the first air chamber (K1) and the second air chamber (K2) temporarily in a first position (G1) of the piston (3) with respect to the outer cylinder (2). |
