Abstract
Official abstract text for this publication.
In a fluid circuit for an air cylinder connected to a switching valve provided with exhaust ports, a head-side pressure chamber is connected to the switching valve by a first pipe, and a rod-side pressure chamber is connected to the switching valve by a second pipe. A first restrictor is disposed at a connection point between the first pipe and the switching valve or in the vicinity of a first output port of the switching valve, and a second restrictor is disposed at a connection point between the second pipe and the switching valve or in the vicinity of a second output port of the switching valve.
First claim
Opening claim text (preview).
What is claimed is: 1. A fluid circuit for an air cylinder, connected to a switching valve switchable between a first position and a second position, wherein: the switching valve is provided with exhaust ports, the air cylinder includes a head-side pressure chamber and a rod-side pressure chamber defined by a piston, the head-side pressure chamber is connected by a first pipe to a first output port of the switching valve, the rod-side pressure chamber is connected by a second pipe to a second output port of the switching valve, the switching valve switches between supply and discharge of air to and from the head-side pressure chamber and the rod-side pressure chamber, a first restrictor capable of functioning as a restrictor when the switching valve is switched to the first position and to the second position is arranged adjacent a connection point between the first pipe and the first output port of the switching valve, and a second restrictor capable of functioning as a restrictor when the switching valve is switched to the first position and to the second position is arranged adjacent a connection point between the second pipe and the second output port of the switching valve. 2. The fluid circuit for the air cylinder according to claim 1 , wherein: the first restrictor and the second restrictor are variable restrictors. 3. The fluid circuit for the air cylinder according to claim 1 , wherein: the first restrictor and the second restrictor are fixed restrictors. 4. The fluid circuit for the air cylinder according to claim 1 , wherein: the first restrictor and the second restrictor are meter-in restrictors.
