Device, method for producing the device, chamber device and transfer device

A transfer device, which transfers a displacement of an actuator, comprising:

• a housing, comprising a first recess in which a first and a second plunger are displaceably mounted,
• wherein the first and the second plunger are effectively connected via at least one transfer chamber using a fluid, the effective connection causes a displacement of the second plunger if the first plunger is moved and vice versa, and wherein the transfer chamber is hydraulically connected via a sealing gap with a compensating chamber which provides delayed compensation for differences in pressure between the transfer chamber and the compensating chamber;
• and
• a sealing system located at a first end of the housing, the sealing system including:
• a first tubular body rigidly coupled to or integral with the housing;
• a second body positioned inside the first tubular body, the second body rigidly coupled to or integral with the first plunger such that the second body moves relative to the first body during displacement of the first plunger relative to the second plunger;
• and
• an elastomer seal positioned between the first tubular body and the second body, the elastomer seal including a first groove extending at least partly around the seal and located at a distance from an outer wall of the seal;
• the elastomer seal closing and sealing the space between the first tubular body and the second body such that fluid in the compensating chamber is prevented from flowing past the elastomer seal;
• a tensioning means configured to support the elastomer seal between the first tubular body and the second body rigidly coupled to or integral with the first plunger, the tensioning means acting on the elastomer seal but not acting on the first or second bodies.

A method for producing a device with a first body which has a recess and a second body which is introduced into the recess, and an elastomer, which is inserted into the space between the first and second body in the recess and thus closes and seals in this area the space between the first and second body, with the elastomer having a first groove which extends at least partly along the recess at a distance from the wall of the recess, the method comprising the steps of:

• plasma-activating the first body and the second body;
• providing the first body and the second body with a bonding agent in the areas in which the elastomer is to be applied;
• and
• introducing and vulcanizing the elastomer such that the elastomer is positioned in the space between the first body and the second body;
• configuring a spring to act on a side of the elastomer to support the elastomer in the space between the first body and the second body, the spring acting on the elastomer seal but not acting on the first or second tubular bodies.
