Abstract
Damper, in particular for washing machines with a spin cycle, with a housing having a central longitudinal axis and at least partially encompassing a housing interior by housing walls, a plunger displaceable in the housing along the central longitudinal axis, guided out of the housing and having at least one friction lining recess, fastening elements, arranged on open ends of the housing and the plunger, and at least one friction lining, arranged in the at least one friction lining recess and in frictional contact with opposite housing walls.
Claims14
A damper with
- a) a housing (2;
- 2d;
- 2e;
- 2g) having a central longitudinal axis (3), at least partially encompassing a housing interior (21) by housing walls (24, 25),
- b) a plunger (4;
- 4b;
- 4c;
- 4f;
- 4g) displaceable in the housing (2;
- 2d;
- 2e;
- 2g) along the central longitudinal axis (3), guided out of the housing (2;
- 2d;
- 2e;
- 2g) and having at least one friction lining recess (14;
- 14b;
- 14c;
- 14f;
- 14g), wherein the friction lining recess (14;
- 14b;
- 14c;
- 14f;
- 14g) fully penetrates the plunger (4;
- 4b;
- 4c;
- 4f;
- 4g),
- c) fastening elements (7, 10), arranged at free ends (5, 9) of the housing (2;
- 2d;
- 2e;
- 2g) and the plunger (4;
- 4b;
- 4c;
- 4f;
- 4g), and
- d) at least one friction lining (17;
- 17a;
- 17g), arranged in the at least one friction lining recess (14;
- 14b;
- 14c;
- 14f;
- 14g) and in frictional contact with opposite housing walls (25), wherein said friction lining (17;
- 17a;
- 17g) is unitary and formed of one friction material,
- e) wherein the friction lining (17;
- 17a;
- 17g) has a thickness which is greater than a width of an intermediate channel of the housing (2;
- 2d;
- 2e;
- 2g), such that the friction lining (17;
- 17a;
- 17g) is permanently biased and in friction contact with opposite inside walls of the housing (2;
- 2d;
- 2e;
- 2g),
- f) wherein the damper provides an enhanced free-wheeling effect when the plunger (4;
- 4b;
- 4c;
- 4f;
- 4g) is inserted or pulled-out of the housing (2;
- 2d;
- 2e;
- 2g).
