Quick-action coupling, especially for plain end pipes
First Claim
1. A quick connector for pipes for pressure or vacuum testing, comprising:
- a tubular housing extending in an axial direction;
a spreadable connecting element mounted within the tubular housing and formed as a sleeve, the connecting element configured to clamp a pipe in a connected position;
an actuating device configured to act upon the connecting element to release the connecting element, wherein the actuating device includes a hand lever extending in the axial direction of the housing, and wherein the hand lever has an actuating push rod that extends through an outer wall of the housing;
a piston positioned within the housing and configured to be movable in the axial direction by the actuating device, wherein the actuating push rod is disposed at an angle of about 45°
with respect to the piston; and
a compression spring positioned within the housing and configured to bias the piston in a connected position.

Abstract
A quick connector for pipes for pressure or vacuum testing includes a tubular housing extending in an axial direction, a spreadable connecting element mounted within the tubular housing, formed as a sleeve and configured to clamp a pipe in a connected position, and an actuating device configured to act upon the connecting element to release the connecting element. The actuating device includes a hand lever extending in the axial direction of the housing. The hand lever has an actuating push rod that extends through an outer wall of the housing. The quick connector includes further a piston positioned within the housing and configured to be movable in the axial direction by the actuating device, and a compression spring positioned within the housing and configured to bias the piston in a connected position.

12. A quick connector for pipes for pressure or vacuum testing, comprising:
-
a tubular housing extending in an axial direction;
a spreadable connecting element mounted within the tubular housing and formed as a sleeve, the connecting element configured to clamp a pipe in a connected position, wherein the connecting element has a plurality of slots extending in the axial direction;
an actuating device configured to act upon the connecting element to release the connecting element, wherein the actuating device includes a hand lever extending in the axial direction of the housing, and wherein the hand lever has an actuating push rod that extends through an outer wall of the housing;
a piston positioned within the housing and configured to be movable in the axial direction by the actuating device, wherein the piston acts on an intermediate piston, which is in engagement with the connecting element, wherein the intermediate piston has an annular piston surface on a front end that faces away from the connecting element, and wherein the annular piston surface has a diameter that is greater than a diameter of the connecting element; and
a compression spring positioned within the housing and configured to bias the piston in a connected position.
