First Claim
Patent Images
1. An engine with an integral actuator for a vehicle, comprising:
- a) an engine housing;
b) a crank shaft rotatably mounted in said engine housing;
c) a pump mounted in said engine housing operably connected to said crank shaft, wherein rotation of said crank shaft produces a flow of fluid from said pump;
d) an actuator at least partially within said engine housing including an actuator portion that extends outside the engine housing coupled to said pump; and
, e) a valve operably connected to one of said pump and said actuator for selectively communicating fluid pressure to said actuator to selectively move said actuator portion.

Abstract
An engine with an integral actuator for a vehicle having an implement needing control. The engine includes a crank shaft, and a pump in a housing and an actuator that extends from the housing. The pump is operably connected to the crank shaft to produce a flow of fluid, such as oil, from the pump to the actuator. A valve is operably connected to the pump or the actuator to selectively move the actuator.

12. A method of selectively extending and retracting an integral actuator contained at least partially within an engine housing comprising:
-
a) rotating a crank shaft of an engine;
b) coupling said crank shaft of said engine to a pump positioned within a housing of said engine to create fluid pressure in said pump; and
,c) selectively communicating said fluid pressure from the pump to an integral actuator to selectively extend and retract a portion of said actuator that extends from said housing.

25. A control system for controlling a PTO shaft on a riding lawn mower having an engine, comprising:
-
a) an engine with an integral actuator, said engine including a housing, a crank shaft rotatably mounted in said housing, a pump in said housing operably connected to said crank shaft, wherein rotation of said crank shaft produces a flow of fluid from said pump, and an actuator at least partially within said housing coupled to said pump;
b) a valve operably connected to one of said pump and said actuator for selectively communicating fluid pressure to said actuator to selectively move said actuator from a first position to a second position; and
,c) a connector link operably connected to said actuator and said PTO shaft, wherein movement of said actuator from said first position to said second position engages said PTO shaft.
