摘要： A hydrostatic transmission (22) including a fluid motor (84) and a variable displacement fluid pump (86) in fluid communication with the motor and having a first and a second, greater, fluid displacement rate. The pump is mounted on a block (78) having an outer surface (211), at least one passage (208, 210) through which fluid flows from the pump to the motor, and at least one first and second fluid bleed hole (213,215 and 214,216) extending from the passage to the outer surface. The passage and a sump external to the pump are in fluid communication through the bleed holes and the void (234) of a sliding element (230) disposed within a bore(218) in the block when the pump is operating at its first rate and the sliding element is in a first position. The first bleed hole and the sump are substantially out of fluid communication when the pump is operating at its second rate and the sliding element is in a second position.

摘要： An evaporative emissions control system (30a, 30b) for small internal combustion engines (32) includes a control valve (66a, 66b) associated with a fuel line (62) and with a vent line (64) which each connect the fuel tank (54) to the carburetor (34). When the engine is not running, the control valve automatically closes the vent line and the fuel line, thereby trapping fuel vapors within the fuel tank and vent line and preventing the supply of liquid fuel to the carburetor. Upon engine start up, actuation of a bail assembly (39) or vacuum produced within the carburetor causes the control valve to open the vent line and the fuel line, venting fuel vapors from the fuel tank through the vent line to the carburetor for consumption by the engine, and opening the supply of liquid fuel from the fuel tank through the fuel line to the carburetor. Also, the present evaporative emissions control system may be used in conjunction with one or more fuel tank sealing and venting assemblies (100a, 100b), which prevent the escape of fuel vapors from the fuel tank into the atmosphere, yet which allow fluid exchange in a closed manner between the fuel tank and carburetor.

摘要： A piezoelectric valve actuation system for an internal combustion engine (10) includes a piezoelectric driver (40, 65, 85) in the form of a pre-stressed wafer or strip including a layer (43) of piezoceramic material such as lead zirconate titanate (PZT). The driver (40, 65, 85) has a central portion which includes an aperture (44) for direct engagement with a valve stem (32) so that the valve (30) is moved between open and closed positions directly by the piezoelectric driver. The piezoelectric driver (40, 65, 85) can have end portions (42) which attach to the engine cylinder head (12) proximate the valve location. The piezoelectric actuator (40, 65, 85) is driven by an electronic control module (ECM) (50) providing electrical signals to control valve operation based various engine parameters along with user input.

摘要： A twin cylinder engine (50, 300), includes a pair of cylinder members (74a, 74b) mounted to mounting surfaces (72a and 72b) of a crankcase (52), and cylinder heads (96, 324) mounted to the cylinder members. The cylinder members are modular components, which may be pre-assembled with components of the valve train as packaged units before the cylinder members are attached to the crankcase. Each cylinder member rotatably supports a cam gear (156) which extends into the crankcase for driving engagement with the crankshaft (58). The cylinder members may be configured for either side valve-type ("L-head"), or overhead valve-type ("OHV") engines, and the cylinder members may also be used in single cylinder engines.

摘要： A drive train (11) for an overhead valve engine (10), including a cam gear (106) driven by the crankshaft (12), the cam gear supported for rotation in the cylinder block (32) externally of the cylinder head (36) and having a cam lobe (214) mounted thereon for actuating a pair of rocker arms (162a, 162b) mounted for rotation in the cylinder head, which in turn actuates intake and exhaust valves (232a, 232b) in the cylinder head. A first lubrication passageway (152) is provided in the crankcase (18) of the engine to communicate oil, pumped from the oil sump (24) by a combination oil pump and governor assembly (120) driven from the crankshaft, to the upper crankshaft bearing (14). A second lubrication passageway (160) is provided in the crankshaft and communicates oil from the upper crankshaft bearing to the coupling between the crankshaft and the connecting rod (98). An air cleaner body (188) includes an integrally formed fitting (194) extending therefrom, which fits within an opening (180) in the breather cover (178) to directly communicate the breather chamber (170) with the air cleaner (58), wherein the air cleaner body may be mounted to the cylinder block in an easy, one-step operation in which the fitting is inserted into the breather cover opening and the air cleaner body is fastened directly to a mounting flange (206) of the carburetor (54).

摘要： A self adjusting wet brake (100) positioned inside the housing (48, 54, 56) of a transaxle or transmission (30). The self adjusting brake assembly utilizes a brake pad (102) having a ramp surface (134) which is contacted by a cooperating surface (132) of a brake cam (104) for brake actuation. The cooperating surfaces allow the brake mechanism to automatically account for brake pad wear and the attendant decrease in brake pad thickness. As the brake pad wears and decreases in thickness, the brake cam progressively contacts the ramp surface of the brake pad to effect brake actuation. In one exemplary embodiment, the ramp surface is integral with the brake pad.
