Buffer and return device for a slide rail in a drawer

A buffer and return device for a slide rail of a drawer comprising:

• a) a plunger having a plunger head on a first end thereof;
• b) a base having:
• i) a base chamber located on a first end of the base, the plunger head being slidably inserted into the base chamber;
• ii) an air passage located between the plunger and the base chamber;
• and
• iii) a lower bend slot located on a second end of the base;
• c) a retaining plate having:
• i) two spaced apart protruding catches;
• ii) a lower projection slidably inserted into the lower bend slot of the base, the plunger and retaining plate being movable between an open and a closed position;
• and
• iii) a holding way located between the two spaced apart protruding catches, such that a lock piece of an inner rail of the slide rail is inserted into the holding way and movable between a locked position and a released position;
• d) an elastic element connected at a first end to the base and at a second end to the retaining plate,
• wherein the air passage restricts a flow of air forced out of the base chamber by the plunger when the plunger moves from the opened position to the closed position to reduce a closing speed of the drawer.
