Abstract
In an annular groove carried by one of a pair of reciprocally movable members, a pin extending into the annular groove and a sidewall of the other one of the pair of reciprocally movable members, a seal assembly comprising a ring carried by an annular body mounted in the annular groove for sealing the reciprocally movable members for minimizing fluid leakage between the members, wherein the pin extends into and through a notch carried by the annular body and an end gap of the ring for retarding rotation of and between the annular body and the ring.
Claims17
In an annular groove having substantially axial and opposed radial surfaces carried by one of a pair of reciprocally movable members, a pin attached to the one of the pair of reciprocally movable members and extending into the annular groove and a sidewall of the other of the pair of reciprocally movable members, a seal assembly to be received in the annular groove for sealing engagement with the sidewall for minimizing fluid leakage between the members, the seal assembly comprising:
- an annular body to direct against the annular groove, the annular body having a notch, an end gap severing the annular body, an annular recess and a bearing surface;
- and
- a ring carried by the annular recess, the ring having an end gap severing the ring and a bearing surface that cooperates with the bearing surface of the annular body to define a contact surface to engage the sidewall;
- the pin to extend into and through the notch and the end gap of the ring for retarding rotation of and between the annular body and the ring, and for retarding the annular body and the ring from rotating relative to the annular groove.
In an annular groove carried by one of a pair of reciprocally movable members, a pin attached to the one of the pair of reciprocally movable members and extending into the annular groove and a sidewall of the other of the pair of reciprocally movable members, a seal assembly for sealing together the pair or reciprocally movable members for minimizing fluid leakage between the members, the seal assembly comprising:
- an annular body carried by the annular groove, the annular body having a notch, an end gap severing the annular body, an annular recess and a bearing surface;
- and
- a ring carried by the annular recess, the ring having an end gap severing the ring and a bearing surface that cooperates with the bearing surface of the annular body to form a contact surface in sealing engagement to the sidewall;
- the pin extending into and through the notch and the end gap of the ring for retarding rotation of and between the annular body and the ring, and for retarding the annular body and the ring from rotating relative to the annular groove.
A method of sealing together a pair of reciprocally movable members, one of the pair having an attached pin extending into an annular groove, and the other one of the pair having a sidewall, the method comprising the steps of:
- providing a seal including an annular body having a notch and an end gap severing the annular body, and a ring carried by the annular body and having an end gap severing the ring and offset relative to the end gap of the annular body, the annular body and the ring defining a contact surface;
- placing the seal into the annular groove to sealingly engage the contact surface to the sidewall;
- and
- orienting the pin into and through the notch and the end gap of the ring for retarding rotation of and between the annular body and the ring, and for retarding the annular body and the ring from rotating relative to the annular groove.
