The sprayer has, in the interior of the handle, a flow channel, in which the cylinder element is arranged. The piston is mounted in a freely displaceable manner in the cylinder element, and the cylinder element is open on the end side in the direction of the shut-off valve. The cylinder element and the piston bound, for example, an air-filled gas volume. If pressure surges occur when the shut-off valve is closed quickly, these pressure surges are damped by the piston moving in the direction of the cylinder bottom and compressing the gas in the gas volume in the process.

1. A sprayer for use with a supply line, the sprayer comprising:a handle including an inlet end and an outlet end; connection means arranged at the inlet end of the handle for the supply line; a sprayer head and a shut-off valve, arranged at the outlet end of the handle, which can be actuated by a h
1. A sprayer for use with a supply line, the sprayer comprising:a handle including an inlet end and an outlet end; connection means arranged at the inlet end of the handle for the supply line; a sprayer head and a shut-off valve, arranged at the outlet end of the handle, which can be actuated by a hand lever counter to a force of a restoring spring, including a flow channel which runs through the handle from the connection means to the shut-off valve; means, arranged between the connection means and the shut-off valve, for damping pressure surges; and a cylinder element arranged in an interior of the flow channel, which is closed at an end which is directed toward the connection means and is open at an end region which is directed toward the shut-off valve, and in which a gas volume for damping the pressure surges is located. 2. The sprayer as claimed in claim 1, wherein the sprayer is a water sprayer, and wherein a double-acting piston is guided in a freely moveable manner in the cylinder element and, at one end, has a pressure of the water acting on it and at the other end, limits the gas volume.3. The sprayer as claimed in claim 1, wherein a gas-filled balloon or bellows is arranged in the cylinder element.4. The sprayer as claimed in claim 1, wherein the connection means are formed on a connection nipple, on which the cylinder element is fastened.5. The sprayer as claimed in claim 2, wherein the connection means are formed on a connection nipple, on which the cylinder element is fastened.6. The sprayer as claimed in claim 3, wherein the connection means are formed on a connection nipple, on which the cylinder element is fastened.7. The sprayer as claimed in claim 1, wherein the restoring spring is supported at one end on the cylinder element and, at the other end, on a slide, on which a closure element of the shut-off valve is arranged and on which the hand lever acts.8. The sprayer as claimed in claim 7, wherein the slide is of cup-like design, a valve-seat element which is arranged in a fixed manner in relation to the handle projects into the slide, the valve-seat element interacts with the closure element arranged in the interior of the slide, and the slide has apertures which communicate with the flow channel.9. The sprayer as claimed in claim 8, wherein the slide is mounted in the sprayer head.10. The sprayer as claimed in claim 1, wherein arranged between the handle and cylinder element is a connecting sleeve, which bounds the flow channel and on which the connection means and the sprayer head are fastened.
