Abstract
The present invention provides a hydro-pneumatically operated fastener installation tool (2), including a head (4) having hydraulically driven gripping and pulling means for gripping and pulling the stem of a fastener, thereby to install the fastener, and a hydraulic inlet port (6) provided in the head (4) for supplying hydraulic fluid to a cylinder (8) to drive the gripping and pulling means, wherein the cross-sectional shape of the hydraulic inlet port (6) is non-circular, such that a cross section of the inlet port (6) has a longitudinal axis and lateral axis, wherein the longitudinal axis runs widthways across the tool head (4).
Claims19
A hydro-pneumatically operated fastener installation tool, including a head having hydraulically driven gripping and pulling means for gripping and pulling the stem of a fastener, thereby to install the fastener, and a hydraulic inlet port provided in the head for supplying hydraulic fluid to a cylinder to drive the gripping and pulling means, wherein the cross-sectional shape of the hydraulic inlet port is non-circular, such that a cross section of the inlet port has a longitudinal axis and lateral axis, wherein the longitudinal axis is greater than the lateral axis.
A hydro-pneumatically operated fastener installation tool, the tool comprising:
- a handle adapted to allow a user to grasp the tool;
- an intensifier tube disposed within the handle;
- and
- a head having
- a hydraulically driven nosepiece configured to grip and pull the stem of a fastener;
- a bore for receiving said intensifier tube;
- an inlet port extending from said bore, said inlet port having a non-circular cross sectional area and being in fluid communication with said intensifier tube when said intensifier tube is received within said bore;
- and
- a hydraulically driven cylinder in fluid communication with said inlet port, the hydraulically driven cylinder operatively connected to the hydraulically driven nosepiece to drive the nosepiece thereby to install the fastener;
- wherein a cross section of the inlet port has a longitudinal axis and a lateral axis.
