Abstract
A mechanical system comprising: a tappet, including a body; an insert mounted in the body; a pin extending along a first axis; and a roller element movable in rotation relative to the pin around the first axis. The insert supports the pin, while the body supports the insert, along at least one first direction parallel to a second axis which is perpendicular to the first axis. The mechanical system can be integrated into an injection pump and/or a valve actuator.
Claims18
A mechanical system, comprising:
- a tappet including a body,
- an insert mounted in the body,
- a pin extending along a first axis, and
- a roller element movable in rotation relative to the pin around the first axis,
- wherein the insert supports the pin, while the body supports the insert, along at least one first direction parallel to a second axis which is perpendicular to the first axis.
An injection pump for a motor vehicle comprising:
- a mechanical system, including:
- a tappet including a body,
- an insert mounted in the body,
- a pin extending along a first axis, and
- a roller element movable in rotation relative to the pin around the first axis;
- wherein the insert supports the pin, while the body supports the insert, along at least one first direction parallel to a second axis which is perpendicular to the first axis,
- wherein the mechanical system is a subassembly integrated into the injection pump.
A valve actuator for a motor vehicle comprising:
- a mechanical system, including:
- a tappet including a body,
- an insert mounted in the body,
- a pin extending along a first axis, and
- a roller element movable in rotation relative to the pin around the first axis;
- wherein the insert supports the pin, while the body supports the insert, along at least one first direction parallel to a second axis which is perpendicular to the first axis,
- wherein the mechanical system is a subassembly integrated into the valve actuator.
A method for manufacturing a mechanical system comprising steps of:
- obtaining components of the mechanical system, the components including:
- a tappet including a body,
- an insert,
- a pin extending along a first axis, and
- a roller element;
- mounting the insert within the body;
- assembling the roller element to be movable in rotation relative to the pin around the first axis;
- and
- positioning the pin in the insert while the insert is positioned in the body.
