Abstract
A reciprocating saw includes an outer housing defining a longitudinal axis, a casing positioned within the outer housing, an upstream opening between the outer housing and the casing, a downstream opening, and an egress path extending between the upstream opening and the downstream opening. The egress path includes an upstream portion that extends along the longitudinal axis, a downstream portion that extends in a direction transverse to the longitudinal axis, and a redirecting surface positioned between the upstream portion and the downstream portion.
Claims17
A reciprocating saw comprising:
- a motor;
- an outer housing defining a longitudinal axis;
- a blade driven by the motor to reciprocate during a cutting operation, the blade extending from the outer housing at a blade end of the outer housing;
- a gear casing positioned within the outer housing;
- a motor casing and an end plate coupling the gear casing to the motor casing, wherein the end plate includes a redirecting surface;
- an upstream opening between the outer housing and the gear casing;
- a downstream opening;
- and
- an egress path extending between the upstream opening and the downstream opening,
- wherein the egress path includes an upstream portion that extends along the longitudinal axis, a downstream portion that extends in a direction transverse to the longitudinal axis, and the redirecting surface positioned between the upstream portion and the downstream portion,
- wherein the redirecting surface is configured to redirect fluid flowing along the egress path from the upstream opening toward the downstream opening during the cutting operation.
A reciprocating saw including a motor and a blade driven by the motor to reciprocate along a longitudinal axis during a cutting operation, the reciprocating saw comprising:
- a motor casing;
- a gear casing coupled to the motor casing;
- an outer housing surrounding the gear casing;
- an egress path defined between the outer housing and the gear casing;
- and
- an end plate disposed between the gear casing and the motor casing such that the end plate inhibits fluid flow between the egress path and the motor casing during the cutting operation,
- wherein the egress path extends from an upstream opening to a window located adjacent the end plate, and
- wherein, during the cutting operation, the egress path is configured to direct liquid that enters the upstream opening toward the end plate, where the liquid is then redirected toward the window.
A reciprocating saw including a motor and a blade driven by the motor to reciprocate along a longitudinal axis during a cutting operation, the reciprocating saw comprising:
- a motor casing;
- a gear casing coupled to the motor casing;
- an outer housing surrounding the gear casing;
- an egress path defined between the outer housing and the gear casing;
- and
- a window in a bottom side of the outer housing,
- wherein the blade extends from a blade end of the outer housing,
- wherein the egress path extends from an upstream opening adjacent the blade end to the window, and
- wherein, during the cutting operation, the egress path is configured to direct liquid that enters the upstream opening toward a redirecting surface that redirects the liquid toward the window.
